I myself am thinking of getting both the elite kurzick and luxon, but atm I'm poor as #%!&... Anyway, elite Luxon first. That armor is badass like hell
You are wide thanks to the big shoulderpads and the leggings. You look scary, personally, which armor is the most scary of these, elite Luxon takes them all down.
Elite Kurz, this has got a more "sophisticated" look. Kinda slim, cool shape of the helmet and stuff. This fits well in with a sword warrior (the Luxon is more of the axe type, and not small Forgotten Axes, now we talk big time axes

)
I only wrote bout those 2 cause those are my favs of those you listed. I agree that templar armor looks awesome to, with it's more realistic look and such.
I like sunspear too, it's cool. But not even close lux or kurz

I myself got the Monument armor, as it's primeval, luxon, elite luxon, elite sunspear and elite templar all in one
But now to the finals. I'd go for the Elite Luxon.
