>>11810357 (OP)I think so.
1) some of the finer graphical details are simplified even in GB mode in the GBC re-release
2) the re-release's GBC mode honestly isn't that great, it feels phoned in and your save file is locked to that mode for no good reason, so you have to DELETE YOUR ENTIRE SAVE if you want to play in the other mode (this is so retarded)
3) game was clearly developed for SGB primarily and there are all sorts of cool and unique borders for each area.
