Turbocharger, Supercharger or new GT
Guys I am torn! I have a nice 2007 Mustang GT with 60,000 miles on it. It's very clean and runs great. I have been researching the possibility of adding forced induction to bump of my cars HP but am not sure if the overall cost is worth it Vs. Buying a low miles 2015-16 GT. Opinions??

It depends on what you like and what you want.
The 4.6L engines can put down the power when built and boosted, but it is becoming the bastard child engine these days, and if you don't build (forged) the bottom end, then you are pretty much limited to around 450-500RWHP and if that's the limit then a positive displacement supercharger is the way to go, if you drop the coin to build the engine, then you should go turbo... the latest gen coyote engines are holding above 600 and there's that dealer somewhere in the middle of the country selling new roushcharged GTs for under $40k, hard to argue with that.
If I were doing it today, I'd probably opt for a clean low cost 2013-14 GT, not worry about low miles, replace the short block with a coyote aluminator and then turbocharge it... as a start. But I'm not, my 2008 is a 50K mile, built block twin-turbo, so I can't ever start over.

I considered exactly what you are now. Low mile 2007. I opted for a 2013 Coyote powered car. Better balanced than a 4.6 w supercharger - that is a lot of weight over the nose. I returned my 07 to mostly stock and still had a hard time selling it.

Without knowing your budget or financial situation, my personal bias is to use cash money to upgrade what I have, and OWN IT, rather than finance a newer vehicle.
I thought about trading my [already modified] car in for a '16, but after a test drive decided it would be a lateral move that would continue to cost me for the next 3-5 years. If you have the cash, more power to you, but a one time expense for F/I is a lot less expensive than financing.....
...and you'll still want to modify the new one down the road, sooooo....

Just sharing my decision. I can share the math behind it. 07 worth about $13K, supercharger kit costs $6500 and nets 436 HP. I can get a 2011 with a 412 HP 5.0 for under $20K. I bought my 2013 for a couple thou more so I get 420 HP (with a better looking body than a 2011 - my opinion) and a strong foundation for more.
Since they are both S197 cars, I swapped the lowered suspension, Tokico adjustables and my 18x10's onto the '13 and then sold the '07.
If you have the money for mods, think about what that plus your car can get you in the end.

Whipple kit on an otherwise unmodified 4.6L 3-valve gave me 467 HP, to the wheels, so that's about 550 at the crank. The numbers you quoted for coyotes (2011-412HP & 2013-420HP) are the crank numbers as shown in the brochure, after intake and tune they approach 400 HP at the wheels.
However as I said earlier, there are a lot of ways to go and it depends on where the OP wants to be and what he likes. If the OP is not into the car with any mods yet, it's a good time to step back and consider switching the base car to have something better to build with... and actually, why stop with just looking at GTs, maybe think about upgrading to a GT500, even if it is also a 2007, just sayin'... 5.4L, 4-valve, and supercharged.

Nice, but you are comparing apples with oranges.

I guess I can see how you might see it as blown 4.6 compared to a CAI w tuned 5.0. So yeah, apples and oranges but its still about getting more HP, however you do that.
The 5.0 has a stronger bottom end than the 4.6 so any mods that get each engine to 475 RWHP will be better supported by the 5.0's forged crank and connecting rods. A 60 HP add rather than 200 HP.
Since I do track days with my Mustangs, I'd rather not have the extra weight of a supercharger over the front axle. The heat load is also a consideration. The SC kits need a larger radiator, oil cooler and some sort of intercooler setup to keep from overheating during 30 minute track sessions.
