I've had a 5BW six-speed for over 2 years and absolutely love it. Just got back from a 1,300 mile rally and there was nothing else that could hang over bumpy back mountain roads through CO, AZ, and UT due to the incredible compliance and control of the mag suspension and big torque out of corners. Made me love the 5BW even more and it's a forever keeper (as long as it doesn't fall apart or become a big problem. Great so far in 11k hard miles!)
That said, for the right price, I'd take a 4BW for a track toy and around town weekend/daily beater to replace my recently bought '24 Corolla GR (really fun car too in it's own right!). Waiting for the sub $60k purchase price of a decent option new 4BW.
On that front, if you can swing the upfront cost of a 5BW, it will absolutely hold long-term value much better than 4BW, especially the six-speeds. It's just a fact due to last of breed and unique aspect of a supercharged V8 strapped to a six-speed. So, long-term ownership cost could arguably be cheaper with a 5BW.
