"1" is objectively the best frame since it's the first, and will always be the best frame set due to it. But the number is a big issue, because can you imagine having "1" and not "2", or "2" and not "1", or, God forbid, "3" and neither "1" or "2"? Just wouldn't work for me.
As for what they look like, I can't remember. Although with rank loss coming, this is probably the last season you'd have a chance to get it easier (unless you got lucky). Unfortunate.
