What bitcoin miner should i use?

I currently im using BitMinter. Im shur there is currently better, what do you use?

I use cgminer.

well how exactly dose it work?

cgminer is probablt he most efficient (gets you the highest hashrate). But it takes quite a bit of setting up and troubleshooting can be a bit tricky.

Otherwise, guiMiner is pretty good. Its simple, easy to use and troubleshooting is pretty easy.
