Not even low key my fav console.
Neo Geo AES has my heart, but logically I know the PS3 is superior in every way and in every way to most other consoles.
Right off the bat PS3 is basically the king of audio for any console, able to pump out 7.1 uncompressed lossless audio. Take that it can play PS1, PS2(if you got a fat boy,) and PS3 games, is completely region free for PS3 titles so you can pop in that Japan exclusive without doing anything, and to top it all off plays blu rays. I mean come on. The PS4 literally does like half the **** it's predecessor could. Best console ever.
If you wanna max your PS3 quality I recommend getting a Marseille mCable which actually improves anti aliasing and draw distance. I know it sounds insane that a video cable can do this, but it is actual black magic. Then swap in a 1Tb SSD which will noticeably improve boot and some load times as well as giving you much needed storage. And keep it cool, apply new thermal paste to an older one because the factory stuff they used was very cheap and will dead your console if it is dry and gets too hot.
