Seen people mixing some things up. Mentioning duels, pubs and clan wars in the same context.
Let's look at it this way:
Tournament Scene: Obviously the lifeline of Native with bunch of great players, organisation and teamwork .cRPG tourney scene is not so big but there are clan matches, can't really tell you how are they since I don't play them but I'm pretty safe to say that Native takes this round.
Pub: Well I think we all agreed here that cRPG pubs for all the reasons mentioned are the superior.
Duel: Well this is a tie braker for me, I'm incredibly interested what people that really know both scenes think, I don't know which mod has the superior duelists, not even sure how to determine it since you pointed out that in Native everybody has the same gear and build basically while in cRPG which is the beauty of this mod you decide on your own what you abuse the best and use it.
* There is also Strat, one of the reason the tourney scene ain't that big here, a feature native doesn't have and I'm sure a feature that with customisation attracts and still keeps allot of players playing cRPG.
Mind you my Native knowledge is very limited and my "info" is drawn from posts in this thread, so this is by no means an expert analysis, just an observation from a bystander.
