A corvette is faster, more reliable, easier to work on, easier to tune, has a massive replacement parts supply, and has an incredible aftermarket following to do just about any mod you can think of.
It's also staid, unimaginative, and nearly impossible to be unique or stand out in any way, because everything's already been done by someone already.
I could have LS swapped my Porsche when the flat 6 gave out after a race. There's even a company that makes whole kits for that, and Haltech makes pre-made wiring harnesses for any LS that would have made the entire swap incredibly easy, plug and play, and I could have had a cheap and easy 400+ whp car with limitless engine tuning potential. Instead, I bought an F136S, and went through the atriciously long and difficult process of doing everything from scratch myself for an engine with comparatively no aftermarket support, and very limited recources to find information on stuff like the engine wiring harness.
Sometimes, it's not about having something that's quantifiably 'the best'. It's about having something special. Same reason I bought an Alfa Romeo when the Giulia came to the U.S. It's not the fastest car in the world, or even it's segment/price, and the aftermarket is proving fairly slow to grow, but I love it. It just feels special, and I know that if I had spent my money on another new BMW, Porsche, Mercedes or Jaguar, I wouldn't get the same feeling I do from my Alfa. They are all great cars, and I still enjoy owning and driving them, and each one has it's niche it's good for, but the Alfa is the one I take to work every day, or go run errands, or just cruising around town hunting a burrito. It turns an otherwise uninteresting trip into an enjoyable experence.
To bring it back to the original question, it comes down to personal prefereance. The vette is faster and easier and etc etc, but uninteresting. The Maserati will be harder to live with, but is special.
Apologies for the ramble, I'm a bit bored at the moment.
