Just ask Stazi how much boost my car makes from a stand still........I took him through first gear. 
My blower makes max boost practically right after I floor it. Benefit to having the roots blower.
For everyday driving the S/C is seriously the way to go if you want more power all the time. Like Percyguin said mine hardly affects my gas mileage. That is running a Mustang GT MAF, chip and 42# injectors. If you want ridiculous power, turbo is the only way to go. You can run more boost, which also requires more tuning, and wears down you engine fast. A lot of give and take when it comes to performance. If you want power sometimes run nitrous. Nowadays it is real safe. Like SleeperZ said running N/A for high power is pointless. To even build up the engine to run 170 hp you could very well buy any of the power adders above.

turbo or nitrous would be more cost effective and make more power IMO.
Not when it comes to tuning. Don't knock it until you have ridden in one....

If you are talking about SZ the reason you did is because stazi was spinning his tires, Thats what happens when you have power....
How do i know this, because i was in the carrrrrrrr.

Oh For Gods Sake! I don't check the forums in a day and it all goes to heck. First of all boost is boost and both SCs and turbo's are difficult to tune right.
Both will negatively affect fuel economy depending on circumstances. A light foot on the throttle can do wonders for your mpg. A turbo is arguably better for fuel economy since it operates off waste gasses from the engine and not a belt that needs engine power to turn, they say the cruise exhaust velocities would spin the turbo a bit and make the engine breathe a little easier.
Yes a SC is easier on the engine, but that's because it's weaker. At least on the Zetec they are. Pound per pound of boost, all SC for the Zetec are weaker than even the smallest turbo's. My first base setup for my car using a turbo more suited for a 1.6L engine put out 145whp and 156wtq. That's only 5hp less than the base Jackson Racing unit but I only revved to 5800rpms and the JR setup was revved to 7000rpms. That was done on stock fuel and ECU on a lean AF.
Like I said the HP was slightly lower than JRs list figures, I killed the SC on TQ. A stock JR will barely do 130wtq and at similar boost levels will always e 20-30wtq behind a turbo.
The reason this is is because a SC has more lag than a turbo. Yes, lag. Because the SC is tied to the crank and rpms so it doesn't reach full boost until near the redline. My turbo hits full boost by 2700rpms. A properly sized turbo will hit full boost by 2500-3000rpms. I believe a standard t3 super 60 will do full boost around 3500rpms, and that's way faster than the JRSC or even a vortech.
My initial setup also cost around $800 and lasted for over 20k mi before I decided to upgrade and push more boost, so if you are pretty mechanically handy a turbo is cheaper to do. If not and you want the closest thing to a bolt on for our cars, then the JR is it.

i was sceptical about the JRSC how good it would be until i got it, and it has surpassed my expectations. i drive lead footted and its hardly effect fuel economy compared to when it was normally aspirated. its now at 207bhp @ 7PSI at the flywheel (160bhp at the wheels i think - but UK bhp is slightly different to USA bhp). personally i reserved judgement on critising the JRSC until i had tried it myself. i had read such good reports from dozens of people on focaljet that i couldnt resist, and i have made the right decision.
as for being difficult to tune, it took them 30 minutes on the dyno rollers and about 7 runs to tweak it to perfection - hardly rocket science!
i am getting 370 miles to a tank being lead footed, i know someone with a zetec turbo 2.0 who is getting 150 miles to a tank. and he has had alot of teething and running problems etc.
i know i could get alot more power from turbo but i dont want the bad economy (fuel is nearly �£1 per litre in UK - i.e. 2 dollars per litre), dont want bad reliability, i just want a decent quick car to use every day and he comfortable to use on long journeys. plus i didnt want it off the road for months while the conversion was done. if i wanted big turbo BHP i would get something RWD or 4x4 i.e. Jap or cossy. that way it would be able to get all that power down aswell.
i'm not pro S/C or pro turbo, but for my needs the S/C suited me and i'm well happy with the results and from what i can see the positives outweigh the negs.

No offense but the turbo guy was definitely not tuned right. There's no reason that a turbo should run that crappy. It should get as good of gas mileage as a SC. Most likely he has doing something dumb like a BOV and a SAFC.

how is a SC easier on the engine? It would put the same strain on an engine as a turbocharged vehicle if they were putting down the same power. An IC or some type of cooling is needed for a reliable setup and it still requires larger injectors and maf and chip so how is it also easier to tune?
in the end you will end up spending as much for a turbo kit as you did the SC (after it is properly tuned) and still make less power.

I don't knock the JRSC, even though it is weak compared to what else is on the market. I'm sure I wouldn't mind one but for the $$$ spent and the gains being seen it just doesn't add up IMO.

It really boils down to personal choice.
I would go SC for daily driver.
For a track built car (either auto-x or drag) I would go turbo.
Of course for a drag car, I wouldnt use a Contour.
