Unity is extremely flawed but I'd say it's still worth playing, at least as a curiosity. They did good work with Paris.

Yeah, the low difficulty is definitely an issue since it discourages stealth. Unless you want to do it for its own sake you end up with a slower and more difficult solution to the same issue.
It does make for a fun subversion in AC Brotherhood when you fight the Borgia Captains, though, since they'll counter all your counterattacks in a needlessly fancy fashion. Ezio finally found someone that can out-Ezio him. Of course there's still ways to one-shot them, but it's fun that it's there at all.
IMO no AC really succeeds at making satisfying difficulty, since Unity mostly makes use of stat bloat and the very annoying feature where melee enemies are completely trivial but the moment you get a third opponent he'll start spamming pistol shots at you, which you can only avoid via rolling or attacking them, making things take even longer. And if you try to disengage you can't roll anymore, so you'll get shot unless you manage to put a wall in between
