I don’t have a favorite variation specifically, but I like a lot of the green colors (Emerald Crystal, the cooler Acid) and Bedrock Earth. If there was a Bluesteel variant of Metal Magic, that’d be up there too.
Conversely, I HATE Venom Poison and Nova Plasma, so it pains me to see that those are the variants you see whenever Poison or Plasma Magic are brought up. Hell, the UGC Plasma Magic Circle is Nova instead of the base Gamma, which irritates me to no end. I also mentioned purple Acid, which is fine, but I just like the green variant more.
I like yellow thunder more than any other thunder, spring water is my goto, and green ice is also pretty cool, also FUCK you nova is perfectly appealing
