The Z is the best all rounder from that list, it just depends on what you really want from the car.
I find the Z is a good comprimise between having the looks, decent power and most importantly reliability. I've got to be honest tho, as much as I love it I still feel envious everytime I see an evo/skyline/supra driver, I'd rather either of them cars any day of the week and if you've ever been out in a mildy tuned one you'll know what I mean. Way more thrilling than a Z in my opinion.
I bought the Z as a comprimise between performance and reliabiltiy but as much as I love the car I very much doubt I'll still have it by this time next year.
