It has graphical and web interfaces. Has UPnP, NAT-PMP, NAT traversal for automatic router configuration. Has UDP tracker and µTP data transfer protocol support. Even covers IPv6, web seeding, Embedded tracker, Super-seeding and proxy servers. And it auto-updates.

A clean, visually-appealing interface that’s incredibly simple to navigate and cuts down on clutter by allowing any element of the UI not needed to be hidden.

The application automatically manages bandwidth it takes up to not get in the way of other Internet-dependent activities.

Cons
Con Proprietary
No source code is publicly available. As such there's no way to independently check what security and privacy features are implemented and how as well as whether there's any malicious code or not.
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. µTorrent lacks this functionality.
Con Are known to bundle riskware
In additional to typical toolbar and ad bundles, µTorrent has previously bundled an automatic cryptocurrency-miner called EpicScale even if the user opted out of other bundled software.
Con Inappropriate ads (can be disabled)
Not only does μTorrent have ads in the free version, they tend to be inappropriate ads for scammy things like "meet russian women".
Ads can be disabled in the options. It's important to note that disabling ads (as well as all bundled software and featured content) can be a difficult process as it requires manually editing multiple key/value pairs in advanced settings.
The following keys have to all be turned to false by going to options > preferences > advanced:
bt.enable_pulse
distributed_share.enable
gui.show_notorrents_node
offers.left_rail_offer_enabled
gui.show_plus_upsell
offers.content_offer_autoexec
offers.sponsored_torrent_offer_enabled
offers.featured_content.badge.enabled
offers.featured_content_notifications_enabled
offers.featured_content_rss_enabled
Con Bundles bloat
Installation wizard starting with version 3 offers installing a variety of garbage features including toolbars and ads. And makes the process of opting out of such bundled software difficult. It's possible to find version 2.2.x online (1,2) - same lightweight, feature packed application without all the unneeded extras or ads.
Con Customer support is terrible, do not send them money
Customer support refuses to be helpful. DRM must phone home and support blames you when their website goes down.
Con Does not quickly close after download completes
It takes 24 seconds before folx will close when a download has completed, and this window pops up and grabs focus interupting whatever it is you're doing. Very intrusive.
Con Sometimes it doesn't complete the schedule
Con Sometimes downloads start automatically
Con Difficult to uninstall browser addons
You will need to uninstall the addon and then clear the browser's cache. With Safari you will need to enable the developer menu before you can do this.
Con Useless
Can't download anything without upgrading to Pro paid version.
