If you are talking ground combat, DPS is a bit of a misnomer, or at least not the whole factor.
It is how much damage you can do if you only fire that one method.
If you have two weapons, fire special attack, cycle to next weapon use its special attack, then fire a couple bolts and cycle back to special attack of first weapon, you get higher then DPS settings.
I use wide beam and targeting weapons, and cycle back and forth getting both attacks in, effectively increasing the DPS. Especially if enemies are in a group, or have the exposed targeting, then there is a bit of skill to hit next exposed enemy, cycle to weapon with that special ability, fire, cycle back to wide beam, use it on a group, then fire a couple bolts.
DPS only matters if that is the only attack you use on that weapon, and if you do nothing else while waiting for the counter to reset ability to fire that usage of weapon.
i have to admit i prefer the split beams over others, but the cylindrical attacks are also very effective at hitting many targets.
also, with some of the higher "level" enemies like swordmasters, i've noticed since the last open beta build that you wont always get an instant vapourisation while they're exposed now, before it was, or seemed, a 100% certainty but now, not so much.
but seriously, get a bat'leth.. they're insanly fun!
