That is a really good list. I am currently on credits myself and was on Soldo/Goldo before all the drama. Before that, I was on Arionum.
But I would like to point out that Arionum is no longer CPU only. Also, Yesscrypt coins like Yenten and Eli are also very GPU minable now. Oh, and I see XUN on there, pretty sure that one is cryptonite which is also very GPU minable... I know that for sure because I GPU mined some XUN. I really like XUN actually. I really like most coins actually until they turn out to be crap or have crap developers. So far, the list you shared is still really awesome.
But as far as CPU goes, I prefer to only be on coins that are truly CPU only... at least at the time when I am mining them. Of course it's true that eventually someone can develop a miner to mine a CPU coin with a GPU as was the case recently with Yesscrypt.
But yeah, that's why I'm currently on credits which is the Argon2 algo which so far does not have a GPU miner. This seems to be a challenge similar to what we see with ASIC vs GPU. I really like the idea of having strong CPU only minable coins. I'm not sure why I think this is important. Maybe for diversification and accessibility of mining to people without expensive GPU funds. But then again a strong argument could be made against CPU coins because of the likelihood of botnets.
