Honestly I would say that there are pro's and con's to them all...it all ultimately depends on your needs and driving style. I.E. what do you want your truck to do, and what do you use it for the most? If you answer these questions, then you will have answered the question in this thread all together. Just my .02

Look at the dyno graphs between a magnacharged truck and a procharged truck. Ranwalk posted some a long time ago of his 6.0 with a D1 on it which ran pretty good but in comparison to a lot of the maggy graphs floating around here, he was out-gunned into the 4K range where his graph seemed to really take off.
Me personally Ill take my table top flat TQ curve and go beat up on higher HP vehicles street light to street light in 4hi. Thats what I loved about my 418 stroker with a 4K stall, now I can have that same power but no driveability problems and a 2600 stall

root style blowers are good but i would take a procharger over one any day because i can cruise around town and not even notice it there if im not into the throttle,it doesn't affect my gas mileage either. as for low end torque the root style will beat a procharger if its the base model p1 but as soon as you step up to a d1 "just one step up on the procharger scale" you will get stomped out threw the whole rpm range and if you want to do it right go with a f-series set up and you will be scared to even touch the throttle ... besides i like the under hood appearance looks on centrifugal better than a roots , centrifugal looks more custom ....

With regard to the low end torque, you'd need to have a procharger setup to deliver some mad boost down low to compete. If it makes that much boost at 2000 rpm, I'm guessing you're needing some way to limit boost up top. It won't do both. Yes, if you set up a procharger to ultimately deliver 15 psi, it will compete well with a TVS pushing 10psi.
I'll take my maggies against the centri's any day. I've even heard how "bad" all of the maggie"s low end power is. "Uncontrollable" is one arguement. That's a joke. They say it's not an asset simple because they can't make it.
In a heavy truck, just about any maggie will do fine if you're not wanting big power numbers. They are good at moving heavy things easily. Before the TVS came along, a centri would be my choice for a lighter ride. Now, I'd choose the TVS up to 700 rwhp+, and turbos for power levels over that.

.
but then again thats what a stall is for .. a 3k stall will build about 3lbs of boost on a p1 from the get go and that is more then enough.

I have a hard time comparing the TVS to the MP122 because of the weight difference in the GMC vs vette. Also my TVS vette has a six speed manual tranny compared to the 4L80 in my truck. Either will get into boost under 1500 rpm. I can't say there's anything the TVS won't do better than the MP122 though. If you're not looking for 500+ at the wheels, the MP122 does have one advantage......it's cheaper.

i dont know how you can say that a 15 psi will compete with a 10 psi tv when i run with the pound for pound in the quarter mile now, the only differance is they pull me early and then i pull them late, its a pretty even match in the quarter mile psi to psi on evenly matched blowers unless your talking about needing a 15psi p/c to compete on the low end with a 10 lb tvs...
I guess I'm more into street performance. I just don't see high rpm too often and I value the power from the low end boost. I don't doubt that a centri with a high stall pushing similar boost would be better on the track. It's pretty damn hard to move a heavy assed truck no matter how you choose to try to do it. My older brother told me years ago how stupid it was to try to make a heavy truck haul ***. He was right.......and I'm still trying to do it

well thats the thing any body can make a light car fast , but to make a truck fast is sick!!! and what does it for me is the look on peps face with these factory "race cars" "srt8's, mustang cobras/gts , subaru sti and evos when they get stomped out by a truck..... nothing is better then that!!
this is me racing a srt8 300 b4 i had long tubes , exhaust , custom intake... http://s661.photobucket.com/albums/u...t=VID00018.flv

I have the pleasure of driving both. Instantly loved the Supercharged Denali, just like everyone on here says instant 2 second or more drop 0-60 (I went from about 8.5 down to about 5.9).
Thank God for all the experts on this forum who recommended a different stall converter for the procharged Escalade. Installing a Yank 3200TT brought my 0-60 down from about 6.9 to about 4.9 and just as they said it would, turned my frown upside down. Bit of a problem with torquesteer when really get into it now, but at least the vehicle performs now.
But now all this TVS 2300 talk has me drooling. Oh dear.
Bottom line though, don't do the procharger unless you do the torque converter too, otherwise you will be disappointed, is my experience. Good luck with your choice.

Actually, that's an excellent point. You should figure the cost of a new TQ converter in the overall price of a drivable centrifugal-powered vehicle.
