What's wrong with the controller? Had mine since launch, fine after heavy use. The battery is not fantastic though, wasn't impressive from the start.
Never really understood the fanboyism these comparisons invoke. Let's be honest the consoles have been more or less the same for generations now. It's not like comparing grades of PCs, they are more or less similar hardware shoved in a box with 90% of the same games, there is nothing to really get excited about within the differences in my humble opinion. I would have happily stuck my hand into a draw and taken a PS5 or Xbox at random and handed over the £450.
