If I was offered the choice, I would choose VoTG, simply because I have played dozens of RB CG games, not many surprises left really. Now dont take that to mean I wouldnt play RB again, I would in a heartbeat.
RB is the original, it set the bar that all others will be measured against. Tactics have been refined over the last 15+ years that RB has been in use. Even so much as 5 years ago tactics were still being developed, I believe the "no pass option" or "ELR strategy" is relatively new.
If you break it down and put it under the microscope, I think you would find RB lacking. Its a great game.....for the German, not as much fun for the Russian.
And dont take that to mean I wouldnt play the Russians either, I enjoy playing the Russians too. They just arent as much 'fun', for me at least.
One of the biggest things to consider is that when RB was released, there was a lack of ASL material. It was an entirely new idea and an entirely new map.....more importantly a REAL map. Now there is almost an overabundance of ASL material, multiple scenario pack TPP's out there, two other TPP publish 'historical studies'. We are inundated with new material, no longer will ppl play the same HASL module over and over as there is just too much new stuff coming out. Back when RB was around, the only new stuff we could count on was the Annual and pray AH (followed soon by MMP) put out a module.
Will VotG stand the test of time? Its really, really hard to tell, but me thinks the deck is stacked against it, and its got nothing to do with the quality of VotG either.
