Pro Easy editing in a tiled view
Tiled view that shows your image tiled in the editor, and permits you to edit it as you are seeing it tiled. If the brush passes out of your texture, it will just automatically wrap back the painting to the other side of the original texture, while permitting you to paint and see the results on any of the tiled "clones" (the shortcut key to activate this is w by default).
Cons
Con Subscription model
Illustrator CC requires a $19.99/mo (minimum) subscription to use. Adobe no longer sells previous versions of Illustrator.
Con Heavy use of CPU/RAM
Con Steep learning curve
Con Very slow
Even in very good computers Illustrator is very slow.
Con You never truly own this software
As soon as you stop paying you to lose access to the software. This should be illegal.
Con Install useless and intrusive software
When you install any Adobe product it also installs lots of useless and intrusive software and services.
It adds two services and up to three auto-starting software that runs when you start your operating system and keep running constantly. One is for auto-updating, others for "checking" if you are not a pirate and some others that seems to be just to collect information.
Con Imprecise coordinates
Oftentimes your 140 is 139.9997 and as a vector program it doesn't rely much on precision.
Con No proper selection mode
In a vector-art program, the critical selection mode is the one in which objects must be fully enclosed by the selection marquee to be selected. In the simple example shown here, selecting all the circles should merely require you to draw a selection rectangle around them. But in Illustrator, there's no way to avoid selecting other objects as well, even though they're not totally enclosed by the selection box. Year after year, Adobe fails to fix this bizarre oversight, making Illustrator a tedious pain to use.
Con Buggy
Software can be very buggy at times.
Con New features are not tested thoroughly
Since releases are so often and with little time between them, usually new features are not tested a lot and this can bring a lot of bugs with them. Which fortunately are quickly patched in the next release.
Con Documentation is lacking
Krita's official documentation is incomplete in some areas, especially for new features that are constantly added. But this is compensated with it's great design and usability which makes it easier to understand how things work.
Con Poor touch controls
They are still pretty much a WIP. But they are getting there.
