Best Coin To Mine?

I usually mine ETH with my GPU and Monero with my CPU. But it is really hard to find pools that are willing to support small time mining these days so I usually end up not even making what I spend on power. Especially monero pools. If I were to recommend a starter, GUI miner, I would highly recommend nicehash despite the recent hacks which are very common among pools. Here is a link to their app https://miner.nicehash.com/
It essentially benchmarks your pc to find out what currency makes the highest return for your hardware, then allows you to start mining. All pay is payed in BTC and they are good about paying on time and not overcharging with stupid fees.
