This is ofcourse as said pretty much a personal preference. In my opinion only point that the R-spec lacks vs. V Spec is lowend. It's not weak in any sense but V Spec is better and I have no problems admitting it. On the other hand it's more linear than V Spec so some (like me) might find that type of an engine more driveable. From mid-top I feel the Go is not left behind.
But as said change the 5p internals and you'r good to go. Also it does not make the engine any worse if it needs to be tuned differently than others. In case all other engines would tune like V Spec and then V Spec came with tuning characteristics like GO would you then say the V Spec sucs ?
