I use this pool and i am happy with the results:
https://0-100-pool.burst.cryptoguru.org/

0-100 means that you don't get rewarded if you find a block but you get all the rewards (%100) from your historical shares. I started with https://50-50-pool.burst.cryptoguru.org/ when i first started to mine in January and it was horrible. I was still plotting my HDD's at that time maybe that was the reason. (probably not, see below) I wasn't making the coins the calculator was saying. (https://explore.burst.cryptoguru.org/tool/calculate)

In a 50-50 pool you get half of the historical shares and half of the block reward. The problem is you'll never find a block unless you have over 100TB. So I was just wasting my time on 50-50 with my few TB's.

0-100 guru is the best if you are mining on a few TB's  like me.
