Pros
Pro Free, ad-less and open source
Transmission is free, ad-less and open source software licensed under GPL with parts under MIT with source code available here. Being open source allows anyone to check if the software has no malicious code, is secure and respects privacy.
Pro Very minimalistic, straightforward design philosophy
Transmission is great for getting things done without looking too much under the hood. It still has advanced options, they're just tucked away from sight.
Pro Very lightweight
Transmission-gtk uses only 17 mb of RAM in idle state and 24 mb in download state.
Pro Native Mac, GTK+ and Qt interfaces provide seamless integration with OSX and Linux systems
Transmission works well on OSX and various distributions of Linux due to having interfaces natively developed for those operating systems instead of haphazardly ported.
The Mac interface is written in Objective-C, uses dock badges and Growl notifications while the GTK+ interface follows GNOME Human Interface Guidelines and has support for popup notifications, desktop sounds, and a system tray.
There's also an unofficial port of Transmission-Qt for Windows.
Pro Full-featured
Transmission covers basics such as Prioritization, Selective Downloading, DHT, PEX, LPD and Magnet URIs. It has graphical, web and command line interfaces. It includes MSE/PE for security. Has UPnP, NAT-PMP, NAT traversal for automatic router configuration. Has UDP tracker and µTP data transfer protocol support. Even covers IPv6, Web seeding and Local Peer Discovery. And it auto-updates.
Pro Has a command line interface and a daemon
Transmission can be used in text-only mode via transmission-cli
that includes a daemon (transmission-daemon
), a CLI and a web client (accessed on http://localhost:9091 by default).
Pro Works great on a seedbox with its web interface
Transmission has a web interfaces that can be used to remotely control torrents. It's great as a seedbox (a dedicated private server for uploading and downloading content) due to built-in webseed support.
Pro Pre-installed on multiple Linux distributions, including Ubuntu
For those who prefer Linux, the Ubuntu OS comes with Transmission already installed, so you can get your torrents up and running immediately.
Pro Headless software
Just put it on your server, SBC or even your old phone and you have your own torrent server.
Pro Lifetime updates
Pay once, get updates forever.
Pro Interface will be familiar to those coming from Photoshop
The interface, especially the Photo persona, is laid out in way that's very similar to Photoshop - a panel for icons for tools on the left, a panel for information and settings on the right.
Pro Compatible with Photoshop PSD files
Affinity Photo can import and export .psd files.
Pro Great performance
Uses the GPU extensively for fast speed on any platform.
Pro Supports layer styles
Layer styles allow non-destructively applying effects to a layer.
Pro Personas allow separation of concerns
At a high level the interface is organized into broad groups of tools called Personas. Personas like Photo for in-depth image manipulation, Liquify for warping the image, Develop for basic RAW photo development and Export for exporting. Each persona displays only those tools that are needed for that task.
Pro Powerful effects
Dozens of visual effects available. All run extremely fast with live previews
Pro Non-destructive adjustment layers
Extensive adjustment layers are non-destructive.
Pro Everything is well organized
Easy to find and use tools.
Pro Runs faster than Photoshop's old code
Pro Lots and lots of undo
Pro The easiest, even easier than photoshop
Pro The perfect combination of Photoshop and Lightroom - all in one
Pro Supports Photoshop brushes, shapes, etc.
Pro Many tutorials
But still it does not actually matter which tutorial you're actually watching, Photoshop or Affinity's, they are pretty much the same.
Pro Very, very cheap for such an app
Pro Has an iPad app
Pro Decent functionality, 100% comparable with Photoshop
Pro Much more lightweight than photoshop
Pro RAW file editing
Pro HDR image editing
Pro Powerful, cheap and lightweight
Pro Very modern and intuitive interface
Pro Color correction
Pro Very fast to learn
Takes about 20 mins, it's that easy.
Pro Growing decently fast
Pro Panorama creation
Pro Imports free images from Unsplash
Cons
Con No preload magnet metadata
Transmission is unable to preload magnet metadata.
Con If data is corrupted, torrent file has to be re-added
If you delete a file that belongs to (finished or not) torrent, torrent will remain in "corrupted data" state and only way to restore it (aside from restoring the actual data file) is to find the original file and re-add it.
Con No broadcatching support
Broadcatching is a method of automatically downloading content as soon as it's available. Broadcatching in BitTorrent clients is usually implemented via RSS. Transmission requires manually selecting each download.
Con No super-seeding support
Super-seeding is an algorithm used to allow downloaders become uploaders quicker. Transmission lacks support for this functionality.
Con The app is hiding too much information
While the app is clearly going for minimalism, some users might feel that the default window that consists of just torrents and their progress bars might provide a bit too little information or functionality. For example, even accessing file lists requires opening up a separate window and navigating to a specific tab.
Con No tracker exchange
Tracker exchange functionality allows peers to exchange information about trackers of a given file. It is another way of ensuring that the file is downloaded from the optimal source. Transmission lacks this functionality.
Con No embedded tracker
An embedded tracker allows turning the client into a server offering an easy way of sharing files with others. Transmission lacks embedded tracker support so another method of sharing or different client has to be used to share files.
Con Written in Python, uses a lot of CPU on fast downloads
Apparently, the speed bottleneck is Python.
Con No built-in search engine
Built-in search engines allow finding torrents to download right from withing the torrent client. Transmission lacks such functionality.
Con No proxy server support
Con Limited selection of plugins
Plugin support was only recently added to AP and not many plugins have been created for the program so far.
Con Can not import gimp or krita files
Free alternatives like GIMP (and Krita) are sort of "go to" apps you can always install and use for simple image editing or graphics on any computer. Affinity's support for Photoshop is great, but having support also for opening and editing GIMP and Krita files would make the versatility and use of this program absolutely superb.
