Don't take a defensive one; ARush is strong enough to make them obsolete.
Reave is very nice, especially if you stack Health gear, but only really comes to its potential with its area version, as ARush is just so strong that it's preferable at most cases. Some Soldier builds base around Reave as the central ability, and getting the area version then takes priority before other powers (yes before ARush even).
If you want to maximize DPS (at the expense of other elements) then Warp Ammo and Tungsten Ammo is a viable option, with Disruptor for different situations.
Neural Shock has an area version and a very short cooldown (3sec) but I never take it because I've found it less reliable if used on enemies with their defenses up.
Slam is one of my favorites. It has a short cooldown (3 seconds), can be combined with Warp to create a Warp Detonation (only requires one additional squaddy for it), works all the same with only 1 point, and works well as a stagger for defended enemies (try going head-to-ehad with a Scion and see what I mean).
Stasis is one of the best powers, but I never use it on my Soldier.
edit: by the way, Zaeed's Heavy Disruptor is always better than Group because it overheats enemies' weapons.
