Yeah, for Wi-Fi or in-game? Larvesta doesn't evolve until level 59, so if you want one for the E4, better go with Chandelure. For Wi-Fi, I dunno. I haven't been keeping up on metagame stuff. Pretty sure they're both good, though I think Chandelure is mostly popular for it's DW ability (which obviously doesn't exist legally yet). Otherwise I think it's too slow and frail for a lot of stuff.
