I've got a Dell USB4 dock on my desk right now. It has generally had pretty good compatibility. The only complaint I really have about it is that it gatekeeps higher PD options behind proprietary signaling so while it can technically output higher than 60W nothing but a Dell device will properly unlock it.

This isn't usually a problem for most of my devices. My Thinkpads just alert me and say they're not charging at full speed, ending up negotiating something like 58W or so. Similar things with other devices. However, I've got one machine that will not even attempt to charge unless it definitely gets 20V/3.25A, which this dock just will not negotiate to for non-Dell devices.
