why etc? It's being raped by asics for years now. There are lots of promising gpu mineable projects that have no asics. Kawpow algorithm coins for example are safe from asics and you will make way more from mining them
As for the OP, Zephyr is the stable choice
Some coins were also ASIC-proof because they used the CPU for mining, but then ASIC manufacturers made the Bitmain Antminer X5. I am sure that using the same principle, manufacturers are already trying to make ASICs for complex algorithms, such as Kawpow.
