Do you mean the Quest standalone version of games compared with the PCVR ones? One site I saw had comparisons of the new phantom covert ops game on Quest standalone vs the PCVR version if I remember correctly. 
Otherwise for straight Rift S vs Quest + Link it should mostly be the same other than the panel differences (Rift S has less SDE but lower contrast compared with Quest) and the compression from using link (apparently unnoticeable).
