What are the rewards for playing sPvP?
From PvE / WvW point of view – you can only get dyes, different finishers, and titles.
From PvP point of view – every game gives you glory (PvP currency) and rank points (instead of levels you have ranks that show how long you’ve played PvP). Amongst other, you can exchange glory for chests that contain PvP only items (armour / weapons), and sometimes glory booster or unidentified dye. The difference in equipment is only in looks, as all equipment is of same power.

There are 3 modes in PvP: hotjoin (in/out at any time), solo PvP (sPvP), and team PvP (tPVP). All give you glory and rank, last two also give you extra tournament chest if your team win. Also sPvP and tPvP include a waiting time (queue), as the team is assembled first.
