Exchange Preferences? (U.S.A.)

I've been using Coinbase but I'm thinking that I'd like to expand and try something else ….. maybe Kraken. I'm open to suggestions.

I mostly just do a monthly DCA, heavy on Bitcoin but I will occasionally pick up some alts with utility (no memes).

I do use cold storage and most of my BTC stack is there, but my alts and a little bit of BTC is currently on the exchange and I plan to (probably) cash that out later this year. For simplicity, I plan to just keep whots on Coinbase there … But I'd like to start using another exchange for purchases.

What do you like and why?
