For what it's worth I changed from the standard Bridgestone to the Falken 452s and they made the ride much quieter / comfortable / wearing very well and handle excellently (wet or dry), at the time they were a lot cheaper that the 'stones or MPS equivalent (I think I used Blackcircle with the club discount); however you do have more choice if your model car requires the same tyre sizes front and back.
My previous car had Toyo T1S which were great on an Mx5, but are not readily available for the 350Z at 18" and 225/245 combo and would stick with Falken in future.
Unfortunately, there is no definitive guide and track day drivers or boy racers may have different ideas about what is best or looks coolest. For everyday driving, the Falkens do just fine and were good value.
For price matching, my local companies for checking are Micheldever tyres or Headley Tyres (nr. Newbury), though in recent times Black Circle seem the cheapest.
