Best rally training in-game

I have been a huge fan of WRC, even though my main interests lies with roadracing.

I recently saw an opinion saying that RBR had the best in-game rally training of all the Rally games on the market, even though the graphics were dated.

Is this true?
Which version of RBR is the best one for rally training?
Or what Rally game has the best in-game rally training module?

Thanks for your input.
