I have a 2005 DH Comp with 06 Fox 40's, saint brakes, hadley rear hub etc and it cost me less than $3000 second hand. So as far as value is concerned i think the DH comp is the way to go.
Also technically speaking the dh comp is a far better design then the Glory, very similar geometry but far better suspension design. by that i mean that it has a rising rate linkage (meaning you can run a softer spring and still not bottom out) and a better axle path (when you compress suspension the whell moves backwards as apose to the glory goign up and forward, which causes it to get "stuck" on rocks). However the glory has a better shock (DHX as appose to the comp's swinger.
But as far as competiveness goes I was getting podiums on mine last year (with 02 Shivers) in U17 and top tens this year in U19's, so they are quite competitive bikes, especially if u can make one light(mine weights 22kg, but still pedals really well).
Also if you ride with your knees in close to the bike don't get the glory because they hit you in the back of the legs
But if you don't try and have a ride of each and see which you like the feel of, as you will always ride faster on something you like the look and feel of.
Good luck with getting your new ride
