Gotliv - The answer will largely depend on your GPUs

Equihash - Zencash and ZClassic are probably most profitable right now but keep in mind equihash ASIC miners are coming soon.
Lyra2z - ZCoin. Not too sure about current profitability but they will be changing the algo soon. Coin is at $22 now but was up to $140 in December, so I think sooner or later it will climb
x17, lyra2v2, blake2s - Shield.  Initially a clone of Verge but I believe a better dev and a large community.  Was at 33 cents in December, at about 2 cents now.
cryptonight - Stellite, Intense, and Monero.  Stellite seems to be the most profitable lately.  Special shoutout to Intense coin though, as I think they have a great project.  Its just slightly less profitable.  Monero usually isn't the most profitable cryptonight coin to mine, but its the most stable for sure.
