Typically, dark/* isn't used often because of its utility. It has few solid attacks in it but a bunch of utility attacks. Most people don't consider the siphon life an attack. Same with ToF, and the end recovery power. However, used properly, these attacks make it near impossible to beat you. At least one on one.
Stone is good because of its front loaded dmg, however, its slow and high end cost make it less than optimal. But there are no other sets that I know of with a DPS that equals stone melee. The utiliy of Stone melee is it's knockdown and disorients. Very useful. But again, high end.
Energy Melee is simple, straight-forward, low end use powerset. But! Its lower dmg than others with less utility until 28 and 32 respectively.
Fire Melee has dots and can be used well. I don't like it because I think its a little slow in the animation department to make it optimal.
Super Strength is widely used, and is a solid all around set. Good DPS plus the RAGE power with increases acc and dmg. Plus the DMG buff from Rage stacks with Fury. And Rage can be made Perma. This is a typical design of most SS users. Solid set
For a secondary, Stomp, if you want mobility, DON'T TAKE STONE ARMOR! You can take a shit pot of dmg, but you can't move. Other than that, do you want resists or defense? If you want resistances against EVERYTHING (including psionics) with great utility, take Dark Armor. Again, high end cost, but the utility is worth it.
Other than that, look at the secondaries to see what each has to offer. Ask about specific sets and I can help you more. Hell is the expert on dark, but I'm pretty well rounded on the rest.
