I know it's about as subjective a thing as you can get, but I find the ergonomics of the DualSense to be atrocious. Like it's so bad that it hurts my hands to play for too long. I also hate the squishy feel of the triggers when they're not using the gimmicky feedback stuff. Overall, I was pretty amazed at how badly they ruined the controller for the PS5 compared to the PS4 one, IMHO.
It's funny to me to see people say they prefer it but hey... some (read: billions of) people also think Twitter was ever worth using. Different strokes for different folks.
I consider losing all the money and XP you've accumulated since the last save to be extremely punishing. Maybe it's just me, but I can't begin to express how much I hate losing progress. Everything I just did for the last X minutes since the last save was completely undone. Nothing to show for it, no XP, no money, no progress toward my next goal. Just a complete fucking waste of time and X minutes of stress I'll have to repeat. It's like I lost power and corrupted my save file. It's the worst feeling in gaming for me.
Yes, I realize you can get that XP/money back but it adds a level of stress that makes my stomach roil even thinking about it right now. No amount of suggestions on how to think of it differently has changed my perception of it significantly. I dealt with it in Elden Ring for a while but it's probably the main reason I stopped playing that game.
Playing a game with similar mechanics but without the death penalty makes me realize how much more fun Elden Ring would have been without it. IMHO of course. YMMV
