Short and sweet answer; If you're into gaming and desperately need a physical keyboard then go for the DZ.
I have both the n1 and DZ and have been using the Z for the last 2 weeks, it is beautifully crafted and looks amazing. At default speeds it outperforms most first generation snapdragon phones and is capable of superclocking up to 1.9ghz (1.5 stable)
That's where it ends for me I'm afraid, the last 2 weeks have been abit of a chore, the phone looks and feels sturdy yet fragile at the same time due to the loose hinge and the phones hefty weight. I switched back to my beloved n1 yesterday and felt europhic as soon as I held it in my hand, it's still a joy to use. It's lighter, feels better and the screen is more clearer and sharper compared to the Z. Don't get me wrong the Z is still an exellent phone and has good Dev support, now that permroot has been achieved Paul, Cyanogen, eViL and VillianRom are all churning out roms for the z.
What really displeased me with the z is the sheer weight of the phone and the issue with the hinge(was firm at first but becoming looser), what I dont want is being lumbered with an 18 months contract and having to deal with a flapping keyboard but only time will tell. (DZ is now living in my sock draw)
I think it's worth jumping ship when there's a significant improvement in hardware, untill then there's not much difference between the Z and the N1
