I haven't used it extensively, but I have not noticed anything other than the odd video initialization at startup that is also common with IIsi and IIfx ROMs. I was hoping that the video issue at startup would have not been present with the slightly older IIci ROM. You can see video of it here:

I'm guessing it happens during boot because it first looks for the more advanced video components and then reverts to the older video setup. That issue could probably be patched, while not a big deal, it would just eliminate initial confusion of whether or not the unit is displaying other hardware defects such as SimasiMac. I was able to get either System 8.0 or 8.1 running just fine.
It seems like the ROMs build upon previous versions (up to a point) given that the startup chime routine reverted to the more simple version with an unmodified IIci ROM. The IIci ROM had to be patched to the earlier routine to get a custom chime to work with the SE/30.
