Depends on your setup. If you are mining with cpu, maybe primecoin or protoshares. If you are mining with gpus then worldcoin. That would be the top profit making as well as most well established coin.

Dogecoin has been around for what, two weeks? Can we tell much about a coin from two weeks of existence?

LTC, highly mined at the moment, well established, but your returns will be lower.

Other coins, quite a few risks, hard to pick out the ones with good communities from those that are around this week and gone tomorrow.

My vote is for worldcoin or primecoin.
