Forza Horizon 4 or Need for Speed Heat?

Should I get Forza Horizon 4 on Xbox or Need for Speed on Ps4. + Reason

Do you have both consoles?

Forza has the advantage that it also supports Crossplay with the PC, but it could not be honest to test it. I had heard it once.

I've only played Forza so far and I'm very happy with that.
Only NFS Heat should be good this time, but I do not know how the multiplayer is there. That's a lot of fun with Forza.

I'm interested in both games

Clearly forza horizon 4!

Have it myself on PC and it is meeegaaa!

Am generally no fan of nfs as it currently stands. I have not played heat yet, but I can't imagine that it can match fh4
