I don't see most RF lenses as anything special. I don't expect any RF lenses to be worse than EF though. I think many EF lenses were already so good it's hard to improve on.
The RF 28-70 f2 is special though, a new speed class for 28-70.
The RF 50 is a different design philosophy compared to the EF. A move from the dreamy to technically perfect and much bigger as a result.
Both the RF 70-00 and 100-500 have different compromise choices. Compact, but less Teleconverter friendly. The 70-200 is downright hostile and refuses to play at all, while the 100-500 plays but not by all the rules (becoming a 420-700 rather than a 140-700 and loss of the stowed size advantage with TC attached).
I think there will be many users who will use some of their favourite EF lenses (with or without other RF lenses) for years on R bodies and may even look for used versions if something happens to their lenses rather than buy RF. eg, an EF 70-200 that can be used with TC may be a choice some want rather than RF 70-200 that can't use a TC.
