To put it simple: The NT01's are better in everyway. They don't need shaved (but can be), they provide much better initial full-tread grip and last longer. I wouldn't hesitate to get them as a great 100 treadwear tire.
Like you said, they aren't the fastest when compared to lower treadwear tires like the Z214, V710, R6, A6, R1...
I've heard very similar comments about them. They seem to be in a great sweet spot pricing wise also.

I'll be running a set of them on my turbo miata for this season of open track/hpde events.
