With which content ? Apple Music or films ?
I've personally found most Dolby Atmos content in Apple Music to sound unpleasant, even with Apple's own headphones, and even with the personalised profile. Is it necessarily related to the quality of Apple's renderer per se ? I'm not sure. Perhaps also a combination of generally poor practices from current early attempts at spatially mixing musical content and Apple's insistence on using a different delivery format than Dolby's AC4-IMS and their own renderer, even though until recently it wasn't possible to easily preview the results while mixing (and still isn't outside of Logic Pro apparently ?).
If you have access to Logic Pro you can try to compare Dolby's renderer (generic profile only) with Apple's (either personalised or not) and nearly instantly switch between them during playback.

I guess that other DAWs would have some feature of that kind as well, perhaps with other renderers. What I find quite interesting about using DAWs is that you can manually enter the coordinates for the location of the object, so you can directly assess whether something that you've heard from x direction was actually meant to be there, and compare how different types of tracks / stems are handled by different renderers.
I've found it quite fascinating to see how the two companies seem to have chosen different ways to render spatial audio, maybe even from a purely philosophical / conceptual / cultural standpoint. For example, Dolby and Apple seem to me to have a rather different conception of how a generic renderer should handle the front / back distinction (the difference is quite jarring when you're panning an object front to back or vice-versa overhead).
This is something I only do very infrequently, but do you play video games ? I recall having quite an interesting experience when I played Returnal on PS5.
