The Advance versions are better. QoL updates, new content, and in the case of the latter two, new levels. The amount of added levels in Advance 4 alone is staggering and they're some of the best fucking levels in the whole series.
Ignore bullshit like
>>12015916. Screen crunch is not an issue since they alter the level design to accomodate it. There is literally not a single situation where you're going to die from an offscreen hazard and it's all reframed to the point where you won't even notice it. The rest, voice samples, colors, and Luigi's sprite, can be fixed with romhacks if they bother you that much. Personally, I think the numerous gameplay updates trump any minor aesthetic changes.
The sole exception is SMB1/TLL. The equivalent is Deluxe on GBC which is missing levels and ACTUALLY suffers from screen crunch. Stick to All-Stars there.

Fixable with a romhack.
