I believe that when buying a pure enthusiast car, only you can answer that question for yourself.
Considering price, a more appropriate comparison would be R8 ($184K CDN) or 911 Turbo ($181K) - but the Porsche can approach $200K+ with a few mandatory options. A 911 Carrera GTS starts at $136K. I would go with the 911 Turbo because I value performance ahead of image, although both cars deliver plenty in both categories. I'd pick the R8 over the GTS.
The numbers:
The 911 Turbo is quicker: 0-60 in 2.6 sec vs 2.9 and quarter mile in 10.6/131 vs 10.9/129
The 911 Turbo stops faster (70-0): 139ft vs 153
The 911 turbo pulls more Gs on the skidpad: 1.06g vs 1.0
The Turbo is faster in the slalom: 48.1mph vs 47.4
The Turbo is 120lbs lighter
The Turbo get much better gas mileage (LOL)

Driveability:
I have allot of experience with the 1986 Turbo and 1997 Turbo. The Turbo can be driven sedately in heavy traffic all day and then be raced on the track all night. It will be 100% reliable, never overheat, be predictable (less so the 86), be comfortable, good visibility, easy to park, provide every convenience, the 4WD system is great in all conditions and it gets decent gas mileage. When you give it the gas or go into a turn, it's JUST AMAZING - even an average driver (like myself) can get a lot out of that car and it "feels" so good. It doesn't just outperform 98% of other cars, it shreds them.
I've only driven an R8 once for about 20 minutes and since it was a friends, I couldn't really juice it. The overall feel is closer to a race car than the 911. Although it's numbers aren't as good, it feels faster, it responds faster and it gives more feedback. It feels more like a fighter jet than the 911. People definitely look at it more than the 911. It sounds great. Daily drivability is definitely poorer, visibility is poorer, it's hard to park because you can't see close to the car, it's less calm, it requires more effort and attention to drive (but that's what allot of enthusiasts value) . The car feels like it's on rails and it always wants to "go".
Be Aware:
Both cars are shockley reliable even when constantly driven hard. However maintenance is CRAZY expensive and parts are INSANELY expensive. You can't take either car to your reliable neighbour mechanic and they are so complex and packaged so tight, you can't buy the tools and learn to do it yourself (I tried). You need to be rich to keep these cars. I bought the 911s to drive for the summer and then flip, the demand is so high that selling them for a profit was a snap.
In summary, if you are looking for a jet fighter that will thrill you and garner much attention, the R8 is a great choice. If you want an even faster car that can be driven every day and is easier to drive at the limit, the Turbo is the way to go.
