Pros
Pro Industry standard
Photoshop is used by professionals everywhere in a wide variety of fields including photography, graphic design and digital art. It is the de facto standard for image manipulation. If you've seen a magazine ad featuring a model, you've probably seen the effects of Photoshop. You won't be alone when using Photoshop.
Pro Trove of plugins that extend functionality are available
A wide variety of plugins that add new effects, improve existing functionality and simplify workflow are available.
Pro Lots of tutorials
There's a huge number of both free and paid tutorials available online. Websites like Lynda.com offer premium high-quality, in-depth tutorials, but there are plenty of free alternatives to be found on YouTube, blogs and specialized sites on the Internet.
Pro A cheaper, standalone version called Photoshop Elements is available
A stripped down version of Photoshop, called Photoshop Elements can be bought as a standalone application for $100.
Pro Includes powerful content-aware tools
Photoshop includes content-aware tools such as content-aware fill that can fill in a select area based on what surrounds it.
Pro Packs a staggering amount of functionality
Photoshop is the most fully featured image editing software available today allowing you to perform highly advanced image manipulation.
It has tools for RAW image adjustments, lens correction, retouching, image stitching, HDR, fixing framing. It supports most professional color modes and file formats. It includes extensive lists of filters, styles, effects, fonts as well as tools for painting, sketching and typography work. It understands both raster and vector graphics. It even includes tools for video editing, working with 3D objects and support for 3D printing.
Pro Integrates with Creative Cloud
You can save all projects directly to the Creative Cloud allowing you to access them from any device and with any relevant Adobe software.
Pro Creative Cloud Photography subscription includes Lightroom
Lightroom is another image editing software from Adobe that's specifically designed for photo editing and managing of large quantities of digital images.
Pro Mobile companion apps available
There's a free mobile app available for iOS, Android & Windows Phone.


Pro Supports animations
Tiles can be animated within Pyxel Edit, with "onion skin" frame overlays to assist in making smooth frame transitions.


Pro Intuitive UI
Pyxel Edit is widely acclaimed for its ease of use.

Pro Tileset extraction
Given an image and specified tile dimensions, Pyxel Edit will extract a tileset with no duplicate tiles. This mostly works for flat images though. If you feed Pyxel "finished maps" you will still get a lot of duplicates.


Pro Tilemap serialization support
Tile-based images (maps) built in Pyxel Edit can be serialized via XML or JSON for easy import elsewhere.
Pro Cheap compared to others
For only $9 (£6), this is one of the cheapest but also one of the best pixel editors out there.
Pro Live tile-update
Instantly see if your tiles are tileable and/or seamless and fix it easily.
Pro Indexed tiles can be used for reusing objects in animations
Cons
Con Expensive
The standalone version of Photoshop costs $19.99/month, though it can be leased as part of the Creative Cloud Photography bundle that includes Lightroom for $9.99/month.
Con Latest versions of Photoshop are subscription-only
While you can still buy CS6 from 2012 without needing a subscription by contacting Adobe support or the cut-down Photoshop Elements, any full-version version of Photoshop past CS6 requires a subscription.
Con Learning it can take some time
While you can relatively quickly learn how to perform a few basic image editing tasks, understanding Photoshop's ins and outs can be difficult. It's partially due to the sheer amount of functionality that Photoshop packs (and understanding that some of the advanced functionality can take a while to understand on its own), and partially due to it being aimed at professionals with little hand-holding for novice users.
Con Very slow
It needs a very power CPU and GPU and many GBs of RAM and still it is so slow.
Con Stop paying, it vaporises
With Adobes adaptation of the "subscription world" PhotoShop too is available as subscription software only. This means it will never become yours. And if you stop paying, you won't have any PhotoShop any more. Whether you are OK with that or not, it also means that PhotoShop for a large part becomes software for those "who can afford it". Or "push cost to others". Like customers of professionals. Which is also a way to become an "industry standard".
Con Affinity Photo is just as good at a fraciton of the price
Switching from Photoshop to Affinity Photo and it's hard to notice the difference quality of a professional's work. They say that PS is the industry standard, but so very few pros that tried Affinity Photo ever look back.
Con Not good enough to be so expensive
Probably the only big advantage Photoshop has over the other free software is the adjustment layers. But still too expensive for just one feature.
Con Batch editing of images is not straightforward
Photoshop is designed to work extensively on one image at a time and while batch editing support exists, it's not that intuitive to use.
Con Asset management capabilities are lacking
In Photoshop asset management is done through a separate program called Bridge. As Bridge is supposed to be a file management tool for not just Photoshop's files, but for files generated by all of Adobe's applications it covers a breadth of capabilities, but not depth.
Con development has stopped -- developer has stated 8/20 that a new version will be released soon
Con Lacks some tools
Con No Linux version
There is no Linux version of the editor.


Con Free version lacks features
The free version of Pyxel Edit is an outdated beta. It does not receive updates.
Con Proprietary, closed-source software
This software does not respect your freedom.

Con Mac version is dependent on Adobe Air
The OSX version of the application requires Adobe Air to run.
