Dunderflipattacks are gonna be way better for riding in pow or off piste cause when you eject pivots can be a pain in the ass, especially in deep snow. attacks also have a way wider toe piece and it feels easier to get wide skis on edge in them. if theyre just park skis get pivots for the culture and the fashion bc white pivots match everything
I will never understand when people say it's hard to click into pivots in deep snow. It's literally no harder than normal. haha
You are right that the wide platform of the attack can create a better power transfer on a wide ski, but the difference is really negligible. The stack height on the attack is something that is nice since it's the lowest out of all the good alpine bindings, but the pivot is the next lowest and still has that low stack height feel.
In reality, the release of the pivot is second to none and the pros that the attacks have in no way outweigh the release values the pivot has. Not to mention the mounting pattern is very compact and especially in the heel it doesn't prevent any dead spots in the flex of a ski (only really noticeable on a soft ski though)
