Like @kerzain I always play the hero - at least the first playthrough. Generally if I do a second playthrough as evil I give up early. I just don’t like being bad.
It’s been a while since I played either, but Tyranny is at least trying to do something different with the RPG hero formula. It reminded me of Sorcerer King - the Rivals standalone expansion is very underrated - which tried to similarly make you a minion of the bad guy to change up the 4X formula.
In Tyranny forcing the player out of the standard good - or maybe good / evil choice paradigm - you’re forced to make some hard decisions with real moral ambiguity. I found it uncomfortable at times, but there was redemption in finding the not-quite-so-bad-choices available. There was satisfaction in taking down some of the really evil characters. And there was some glimmer of good in that for me. Tyranny has stuck with me and I’ve toyed with the idea of going back to it and trying some different choices through the game.
PoE1 was fine as a throwback. Using skills was annoying. The party moved too slowly. There was way too much dialog, especially with the Kickstarter backers stupid inner thoughts. I gave up about 2/3rds of the way through on reading any of it and just powered through the fights to the end. Much less memorable - I have no recollection of the story at all!
So to me Tyranny succeeded in crafting a different experience that I remember. I’m not sure I liked being a bad guy but I enjoyed the experience looking back. PoE1 was junk food.
Full disclosure: I worked on Sorcerer King’s Metarealm feature while at Stardock.
