The supercharger is more power, but if you like modding engines, it has much more headroom for power than an N/A.
Some internals are stronger, but you need premium fuel. The trans life will all depend on how you drive and the maintenance. Supercharged cars are normally Ei'*, but some SE'* have superchargers as well. SSE/Ei'* have more electronic toys, some extra features, but are heavier. They also normally came with better tires originally, and therefore a higher limiter.
When i was car searching for my car, I wanted a car in good condition before i looked at features. I wasn't happy with the Ei'* or SSE'* in my area within my price range.
