Since I launched this topic I gonna be first one to share my two:
1. Firstly it's of course
Monero. The only problem they have it's that you can't join as individual CPU miner so far. Coz there are many mining pools which took almost the whole hash rate.
2. Secondly, I would add
Vincoin Cash - also private blockchain. But in this case, GPU and pool mining are excluded. To make it more decentralize and more competitive. So everyone will have a chance to get a piece of Pie.
Please add your favorite CPU minable coins and tell us why you believe in this?
