Not really, the aim of any /dev manager is to provide you with nodes to access your hardware. The real differences between them are mostly in the way they set that up. To the end user they are mostly the same.
If you are really interested I guess you can compare the Changelogs since udev-17x which is about when the fork took place (not sure about the concrete version number).
Also, some people (at least in Gentoo) seem to be having issues with udev locking their boot process lately. Not sure what the problem is, and not really interested in finding either
