It's a solid MMO: not great but good.
The crafting is deeper than WoW, STO, or RIFT (yes, yes it is--there are more recipes and nuances than casuals realize).
The world (spread across numerous planets) is more fully realized and vibrant that RIFT or STO.
The Crew Skills system removes some of the grind while adding a layer of complexity to crafting. It gives the slightly more complex Duty Officer System in STO a run for its money.
The non-linear storylines are amazing; I've had no less than dozen choices come back to bite me in the arse toward endgame.
