Illustrator, which is essentially abandonware at this point, does indeed suck.

There is one overwhelming defect that kills illustrator, at least for some of us. It lacks the essential selection mode that Inkscape, Corel Draw, Sketch, and others have: only selecting objects that are totally enclosed by the marquee.

Illustrator insists on selecting everything the marquee TOUCHES. The straight-up stupidity of this limitation becomes obvious as soon as you... well, do almost ANY drawing. Did you do a wireframe of a UI, but want to shift a group of labels? Have fun selecting each one separately instead of just drawing a box around them.

The problem may not sound like a big deal if you don't work with this kind of app, but it is. It's a deal-breaker.
