Do you R9?

No

I can't justify spending so much money on R9, but if mats became available for normal players, Piett would get my first one.

No

You can easily beat R9 toons with R7 and R8 counterparts.
Additional protection on some units does not counter act the stupidity of the AI when you play with the right counter.
R9 is a complete luxury, that kinda helps in some scenarios, but isn't needed in any part of the game really.
