Kraken. But (and this warning might apply to more HODLers): don't forget that BSV and BCH-A (now Ecash) don't have replay protection. I've seen people lose quite of bit of money when their other shitforks moved together with their BCH, and usually exchanges won't recover incorrect chain deposits for you.
A very small amount of split dust on each address on each chain is enough to enforce replay protection, but you need to do that before moving your forkcoins. Then sell the forks
