In reply to ianlaw:
Yes and no. Mostly no, I much prefer climbing big cliffs with holds and gear. But once in a blue moon everything comes together on grit and it's more intense and more beautiful than anything that happens when you're plodding methodically up 40m of decent holds.
I'm not much of a fan of the gnarly sandbag cracks - a good challenge, but thoroughly unpleasant. It's the buzz routes, with improbable moves above gear (or above no gear) that have given me some of my most memorable climbing experiences. Routes like Elegy and Archangel are completely unique experiences, the intensity of which simply isn't matched by climbing something with holds.
Then you've got the micro-routes, which are the crack cocaine of climbing. OK the hit is short, just one or two crux moves too high off the ground to be falloffable (although with a few pads you'll probably be OK), but it's super-intense. It's a way of climbing moves very close to your bouldering limit but with commitment, and therefore buzz.
Comparing with limestone it really depends what limestone you're talking about. Pembroke limestone can be amazing - on something like Pleasure Dome the solid, rough, sharp, crimpy rock is a fantastic thing to climb on. But inland limestone in the UK is appalling polished choss. I wouldn't be terribly sad if most Peak limestone was blown up, it's crap (there are a few decent routes, but even those are relative to the shitness of the others, very few would compare to even the worst routes in Pembroke). Although I do have a soft spot for the cobweb and woodlouse-ridden charms of the perma-filthy Chee Tor (and Beeston Tor too).
The other thing about grit - which is all about its accessibility - is summed up perfectly here:
