I am using phoenixd. It’s okay. Easy setup (literally just run a binary and you’re done) and the fees are reasonable. It’s API doesn’t support msats though and it still has some issues staying up.

I would say if you’re willing to run a server but don’t want to manage liquidity, phoenixd is probably your best option rn.

However, since I actually want to manage liquidity and open my own channels for lower fees, I think I’ll move back to LND or something that supports BOLT12.
