It all depends on how you build it. Sometimes they are a PITA to deal with, sometimes they are a pleasure to drive. It costs a little more to build it yourself vs. buying it, but you can modify it to make it what you want.
After 6 or 7 muscle car builds, I dipped my toes into the cobra replica world last year and built this. Overall it was about the same work/price as a full muscle car build (lower end PT build) but I'm pleased with the comfort and ease of use. The top works great and stores away in the trunk.
If you go this route, make sure you first research registration. It varies wildly by state. I ended up spending 2m to register it, including nearly a dozen meetings/inspections and having to buy an older car, having it crushed to do an epa energy credit transfer for emissions exemption. I won't be doing that again anytime soon.
