Sorcery, Hexes, and Pyromancy, oh my!

So I've been playing Dark Souls 2 for like a week now and I've already reset my stats about 3 times. I've gone from a Intelligence build to a Strength build and finally to a Intelligence build that has STR, DEX, and Faith as well. All that said, I found one thing in common: I have always used pyromancy, hexes, and sorcery. Now, that brings me to our discussion. I have used all three and have really jumped around based on the overall effectiveness in PvP as well as PvE. I always did well with sorcery in PvE, but I got my ass handed to me and the same goes for Hexes. Now, I've found pyromancy to be the most effective in both areas when used properly (for me at least). This worked out well for me, but pyromancy spells tend to run out rather quickly. So, I've come up with some a mix of sorcery and pyromancy that I have tested on both PvP and PvE. So far, I have fought 12 other players and defeated 10 of them using this combo. So my question to you is: why you find most useful? Sorcery, Hexes, or Pyromamcy? Or is it some mixture like I have?
