Hold the phone a minute.
You never stated if you intend to keep the stock short block or if a build is somewhere in the future. Moreover, you never stated what your goals are, present or future. YOU REALLY NEED TO EXAMINE THE ISSUES BEFORE YOU BUY.
On a stock motor, any of the systems you mention are good choices and all of them can get you all the power your stock motor can handle. Moreover, all of them are reliable and well engineered. Declaring which is better is very subjective.
I have a polished Vortech HO kit. It made 463 whp on the stock engine. Although it has performed flawlessly, I now have a built stroker and have added an 8 rib kit and pullied the s trim down to 2.95 with a 10% OD crank pulley. My s-trim is now maxed out.
Sometimes I think if I had to do it all over again that I might have gotten a twin screw or a pro charger, but I honestly don't think either would be giving me much or any more power than I can make with the Vortech.
