Great results man, Rahal did a great job.
Appreciate the comparison
It seems like both are great Dr's with a solid reputations and overall results
By what you are saying and what I gathered so far, Bisanga is close to the top of the wave these days and there is a lot of proof and his name is very relevant today, being mentioned very often, while Rahal was there a few years ago and nowadays, while still being reputable by all means, seems like he's lost quite some popularity and there are not many examples of his later work.
I take it that you favor BHR over Rahal, would that be accurate?
