-You don't have lag with a supercharger like you will a turbo.
-You can push more boost with a turbo than you can with a supercharger.
-SC will give you more low-end power as to a turbo which will give you top-end.
-If I remember correctly Jackson Racing quit making D-series SC, so replacement parts will be a bitch to find.
-SC doesn't make too much of a difference, I had a buddy who had a z6 supercharged and it was fast, but not fucking ridiculous like you can make a turbo z6.
-A supercharger costs quite a bit of money, but a turbo build will cost more.
-Depends on what you want the build for. If you do auto x then a supercharger is ideal so you have constant spool and power from the SC, if you are doing drag then a turbo will benefit you more because you are in the high rpm's constantly.
-OR you can go stupid with it and twin charge and have the best of both worlds. Hope this helps, that is what I could think of off the top of my head.
