Any true competitors to the Porsche 911 Turbo S?

This is going to be the most expensive vehicle purchase I've ever made in my life. I honestly don't even know where to begin with my search. The 911 Turbo S has always been one of my dream cars (currently have a 991.1 Carrera 2 and my mom has a 992.1 Carrera S), but I want to do my due diligence and ensure that I don't miss out on taking a look at any of its competitors. But...what are its competitors?

Generally, I want something wicked fast (yes, mind-bogglingly fast) but still luxurious and drivable on my daily commute, which is a mix of curvy roads and highways. Customizability is important, as I plan on keeping this car for a long time and want to build it the way I like it. I'd want reliability to be at least average for vehicles in this class.

The highest I'd want to go is around the $320k mark for the full build.
