Grace F9 Ruby was their top of the line model, very expensive, i have not tested yet.
The next to Ruby is F9-F (Discret 4) with Shibata Stylus that can track stereo and quadro records with frequency extreme up to 60kHz!
I have few samples of F-9F and it’s terrific cartridge easily compete with top quality vintage MM. This is not so expensive as Ruby, but much more expensive than F9E and L. Anyway this is a top choice cartridge! Next to F-9F is F-9U with special U/Utility stylus instead of shibata. I have it too. This is rare cartridge and not easy to find as popular F-9E.
I doubt any modern MM cartidges in this price are close to wonderful Grace F-9-F or F-9-U (can’t speak about Ruby).
Retip is not a problem with Axel in Germany. As far as i know Jico Sas stylus is also compatible (waiting for Neo Sas).
P.S. Those Grace must be loaded at 100 k ohms (not at 47 k ohms) according to the manufacturer recommendations. Honestly, i have never tried to load them at 100k ohms, i believe it will be an improvement.
