yes it is just as durable/reliable/you name it.
If you want a railed version and you know you will be working with a surefire X200 light then you may want the 10-8 because when you take off the x200 adapter the gun will still fit in many standard 1911 holsters without adding any width to the gun.
I choose the 10-8 over the GRP because of small yet useful features. I liked the 10-8 rear sight is very quick with target acquisition while still being very accurate. In addition to that the trigger is a solid design with a set and tuned overtravel stop that cannot be messed with from the front of the gun. Also the fact that the 10-8 uses regular flathead grip screws really screams "duty gun." The VZ diamondbacks on the 10-8 are very grippy while not being overly harsh. Outside of those things there is very little difference between the two guns.
The only thing I really like about the GRP that I wish the 10-8 had was the recessed slide lock pin axle. If you dont want to spend "that much" money then the GRP in standard configuration is the way to go.
You cant go wrong with either.
Ill probably pick up a Talon or GRP in the future and have NH play around with them a little.
here is my 10-8:
