It depends what you mean by better. Generally, the piggybacks are faster & easier to tune. The standalones generally require a much more extensive tuning effort, and are more expensive, but they can give you fine control over absolutely every aspect of how the engine works. Warning: If you've never tuned a car before, you probably shouldn't use either one yourself - improper use of either one can quickly lead to very serious engine damage. Again, it's REALLY tough talking in general here - without knowing exactly what you mean by "better". Better at what horsepower level? Better=easier? Better=slightly more horsepower (even if that slight horsepower advantage costs hundreds or thousands of $ more)? Better on the track? Better for daily driving? All of these are EXTREMELY relevant questions, and need to be answered before a definitive answer can be provided.

The proper order for a bone-stock Mkiv Supra TT is this:

1. All proper maintenance, according to the TSRM
2. Boost gauge
3. GReddy BCC (to prevent fuel cut)
4. Downpipe
5. At least two or three gallons of 100 octane (race) fuel in a full tank of 93 octane (R+M/2) (note: not a half-pint of octane booster)
6. A good set of Z-rated tires
7. Boost controller (note: you can raise your boost using a 10 cent hose clamp - no need to spend hundreds of $ here)

After that, you can worry about optional/additional modifications like cam gears, a front-mount intercooler, an aftermarket intake & exhaust, etc.
