My turn to wade in. This question is a valid one and deserves a serious answer, just like those of you who responded above.
In my opinion, the best Cobra is...the one you like the best. It is just like picking the "best" wine. The best tasting wine to you is the best wine for you.
So, the key here is to know what you want the car to do (a huge task), then to find the one that does that the best for you, including your budget constraints. So research, research, research first, then buy one. This takes a lot of restraint and patience, both characteristics that are sparse when the excitement of getting the car of your dreams comes to the fore.
If you choose from those listed above, the one best meeting your needs, then that is the "best" one for you.
All the best on your "mission."
