Quark algo will not be the future cause it's not good on GPU in comparison to CPU. My bet is now on darkcoin algo, cause 11 hashing algo will make it ASIC resistant for a long long time, yet it's very fast on GPU. Then there's fudge also.
There's HUGE profit to me made off these new algo coin, since there'll be replacing scrypt coins. Scrypt coin value will slowly fall down as the new coins overtake.
I disagree
1) Speeds hashing Quark or X11 on a GPU are pretty much identical from what I have seen using smelter for Quark since its release and sph-miner for X11 and Quark since its release. Quark minimally slower vs X11 with sph-miner, likely since it is more complicated. Since Qaurk hashing speed of smelter is greater than that of sph-miner, it is likely the quark algo of sph-miner could be further optimized, even further minimizing any speed difference.
2)X11 is less asic resistant than Quark. More rounds of hashing don't make it more asic resistant. The 11 rounds of X11 are linear and unchanging, pretty easy to make an asic.. Quark has random rounds that adds complexity and make it more asic resistant. realisticly either one can be 'asic'ed' if there was enough incentive.
Only way X11 would win against Quark algo is if marketing of X11 better than marketing of Quark algo. On their own technical merit, Quark wins hands down.
X11 is not at all ASIC Resistant.
From a pool op sight of things, X11 is much easier to integrate than for Quark was at its time. Quark's algo, and Sif(coin), the algo quark based on, look like someone though about what he's doing while X11 is just a simple daisy chaining of some algo's used from other coins, all findable in the sph lib. The sph lib is a library of different crypto algo's.
So it looks like with X11 someone just sat there, looked at the sph lib which has some algo's written in, rolled the dice 11 times and used the algo which was closest to the number

If you want to, i can start a new algo right away, also based on sph lib, let's call it F4 for example.. I'll add 4 random algo's and throw in a Coin, a Python Library and a stratum daemon
