I think I latched onto your second paragraph, which appeared more general. Also, as I was answering this I was reliving all of the "is this character (or software) better than this one" threads I've read over the years. They're often very general - as if 'better' had a universal, objective definition. Your post acted as a trigger and I reacted. Your main point, about finding that you like some aspect of an older character more than you like it in the newest character, is very valid and it's a good thing to remind people of that sometimes. Over the years here I've observed the hype-hype-hype-build up unrealistic expectations-product release-disillusionment-anger cycle many times. It sounds like you have too. A bit of balance and perspective (as you basically suggest) goes a long way in keeping a hobby fun.

Before they made me they broke the mold!
