I think it's a little strange that you're deciding between these two. If you want bag use and whip, it's either the Extreme or the herbalAire IMO. If you don't care about bag use, why consider the $300 Extreme? As for the Vapor Bros, it's overrated IMO. The Vaporwarez Vaporcannon has the same performance with a better price and 5 yrs. warranty against 2 for the VB. The standard Vaporcannon is only $120 from several sellers and you can get a scale and grinder for free. For hands free use in the $150 range, I think the best buy is the Da Buddha, which has the Silver Surfer technology and reliability at a cheaper price.

I had the V-Tower, which is the whip only version of the Extreme. While it's more satisfying than the herbalAire for whip use, the Extreme comes up short for whip satisfaction vs. the standard whip only units like the above mentioned vapes, because the Extreme's air flow is through wider openings, making for less vapor rich hits. Some people like the wider air flow though. To each his own.

You need to decide whether you want bag fill capability, whip use, or both, and narrow your choice from there.
