wanted to know which is more active from your experience in pvp.

also, if i decide between the two should i go a couple lvls over those markers? example get 41 weapon (with character and gear level up to (42-45) or lvl 46 weapon (character lvl and gear for 47-49)?

i have recently started pvp and went through a couple lower lvl brackets but dont understand how the lvl brackets work. lvl 6 and 15 twink were pretty good with keeping you against the same lvl. 25 and 31 caused alot of ganging from players 2 lvls higher.
