Some people prefer a different "look" even if its less advanced; after all, plenty of users voted here that they preferred the older PS1/Saturn look.
Like you say, presentation can matter more than technology; personally I think Muramasa the Demon Blade is still one of the most beautiful games I've ever played despite the fact it ran on hardware that was underpowered even at the time.
And I would agree with you. Muramasa's my proudest Platinum trophy on PSN.
