Go for the glory. For racing id consider swapping out the rims to, i dont think id trust wtb. I think a white 888 would set it off if you did upgrade the fork.
I got a Glory FR a few weeks ago with a boxxer and it feels really good but I haven't raced it yet. One thing is that the wheel base is a tad short since it's the freeride version. I really like it but I would probably recomend the DH version if you have the choice because it's a bit more DH oriented and comes set up better for it. Check out my pictures of my glory.
it depends on lots of factors, budget and riding style being two main ones. i imagine that the norco is a lot cheaper and as a result the spec is not as good as the glory's. i had a similar problem, ive got a norco shore and i wanted a glory dh but when i tried it, it rode completely differently to my bike. as was pointed out earlier, the glory will have a relatively short wheelbase and the norco will have a really long one. my shore has a longer wheelbase than a glory dh. if id started riding DH on a DH bike then i'd be riding the glory now, so thats the one i'd go for. thats my opinion, hope it helps.
