You've gotta kinda take each recommendation with grain of salt though.
Someone could have taken a ride in a ragged out car with a 10-year-old 6lb Paxton Ball Screw SN93 Huffer under the hood, with no mods and then a ride in a fresh 9psi KB Blown late model GT with full intake and exhaust upgrades, and made their decision and comments based on that.
Or in the same respect, a badly tuned twin screw set up against a tip/top Centi car with a set of ported and polished heads that the owner neglected to mention before taking you for a ride.
Then you've got guys who like to compare two different blown set ups based on the amount of power they're making at a particular boost level.......which is no good either, since the size of the pulley and capability of the blower actually tells only half the battle when calculating boost. A Kenne Bell will make better power (most of the time) at a lesser boost level on the gauge, since it's got a strait, large diameter, short intake runners to back it. No need for long conservative sized runners to generate low end torque figures, since the blower itself produces heaping volumes of airflow at realativly low blower RPM.
You bolt on a Centrifugal blower to a 2V car with a stock intake manifold and it's alwasy going to make less power at the same boost level as a Twin Screw, since the most of the airflow it's making is being backed up in the intake track. To compensate for this, you've ether got to force it in a little harder (to an extent) by swapping out the pulley, or bolt on a higher flowing intake to free up some of that back pressure.
In any case, I've never been in a blown car that didn't make me grin from ear to ear, regardless of what method the owner used to force air into the engine. So try not to take most of these "opinions" based on nothing more than seat of the pants feel too seriously. At the end of the day, the only way to really find out which type of blown car is the faster, is to take into consideration all of the supporting modifications and mechanical factors between the two cars and run em down the 1320 to see who comes out on top.
That said 410's on a streetable blown forged car are no good unless your running Slicks no matter what blower you use. I have been there and done that. I had to walk it out of the hole with a 1.8 60' time and guess what I was getting run down due to the lack of top end from the 410 gear. I went with 355's And I still cant hook up but It is alot better 
. It's neat how people process reality so differently.
