Depends massively on exact spec, use, etc. But in very general terms "biggest isn't best".....
Age of engine and type of heads is also a factor.....

I went with the 11mm RCM iirc
Car is a 98 Type R with a brand new block (S20C and Version 4 heads
I rarely pay full price for RCM parts as the garage I use has a similar relationship with RCM
