I also loved GT3 andGT4, but that was before GT5. I can't imagine anyone, if they are objective, comparing the two games overall, and choosing to play GT4 over GT5.
I actually do. And, as I just wrote in the GT4 forum, I've gone completely back to GT4 now. GT5 is just too empty, soulless, repetitive, restrictive and boring for me.
I can live with the last-gen graphics and physics of GT4 because it's just so much fun...
-There are far more inspired tracks in GT4 (Amalfi, Citta di Aria, El Capitan, Hong Kong, Paris, Apricot Hill, ...)
-You can buy pretty much any car from the new car dealership
-No stupid nannying with XP and levels, just do what you feel like, whenever you feel like it
-Prize cars are actually desirable and usable, and not a complete insult (e.g. you get decent cars for your endurances, but also really nice ones for the easy races); plus you can win (and sell) them over and over and over.
-The whole UI/navigation structure is faster, loads faster and is more playful
-Lots of very decent rally/snow/dirt/special conditions events
-License tests that actually have a use
-There is just soooo much to do in GT4, I sometimes don't even know where to start, because it's all so much fun
If you can live with the pixelated low res graphics of the PS2, then go for it. Oh yeah... GT4 is one of the few PS2 games that support widescreen video output.
