There is so many variables into what you choose.

a stock size turbo on a 3s gives plenty good enough responce with delivering reasonable power (if your only keen on a mild power up)

Now with superchargers there is two types.

1. Positive displacement. These are blowers like the Eaton m90, Toyota SC12 and SC14 etc. These deliver a set volume of air to the engine per revolutuion. These draw the most power from your engine but gives you the instant responce mentioned earlier.

2. Centrifugual. Like Rotrex or Powerdyne do not deliver a set ammount of volume per revolution. These use a tip speed compressor like a turbo (looks like a turbo from the front). These DONT give instant boost, you kind of have to wait for it to "spool" up like a turbo. I put a rotrex on my mates zzt231 (7th gen celica) and with the smallest pulley it made 180 kw atw, around 300 hp at the flywheel, this was at 12 psi @ 8000rpm.


In my opinion go the turbo.
