PS4 if you want better all round grip, it's going to be slightly noisier though

here's a short one to sum up my experience:
I've never needed to worry about wet/dry grip and braking (but please drive sensibly when it's wet la)
it's relatively durable (20k km of hard driving and still looks quite ok), ive used it for 40k km on my previous car and it still looks quite ok
it's easily available almost everywhere (unlike eagle F1/conti CPC6/bridgestone s007 where you need to place orders days before)
it's reasonably priced for what it can do

OTOH, IIRC PS4 is more on par with CPC6, and that's a tier above the MC6, and 2 tiers above the UC6

tire performance reserve (if you can take a noisier ride) is like your savings
no one ask you to use it all in one place, but it's good to know that you have the buffer when you need it one day
