I can play both ways but original hardware have some benefits (zero additional bugs, trophies with PSN, full DS3 support etc.). I also can't explain why but 30fps on PS3 it totally playable for me, while on modern consoles and PC it looks like slide show. And this is on OLED...
Lower resolutions made 30fps easier to deal with but as you go to 4K & higher you will want 60fps & better.
