Hi. Can you define "better" ?
For me, "better" means non-KYC, but for other people "better" may mean something else, so it would help to know what you don't like with Coinbase and Kraken since these 2 are arguably the largest exchanges, so...
I think one exchange that is been advertised at the moment is the Peach. You might check it out if you will. I wasn't asked for KYC document and it comes with very simple steps to its creation. Mind you, be sure to follow through on the steps on how you can fund and sell your coins successfully. A memo would be available for briefing if you will.
