Both good, both have cons.
However, for my preferences, the Bradley is a clear winner.
If you want to cut things primarily, but also have a very tough knife that will tolerate a fair bit of punishment, the GB is your choice.
I think if your priorities are the other way around, you might want the Hogue.
That said, I think it is probably a close race in toughness...both platforms will put up with some hard uses with a smile.
M4 is one of those steels that you can put a shaving sharp edge on and use for a long while and still have a shaving sharp edge. Many others will loose the keen edge and fail to shave (but they will still work for most cutting chores).
The Taiwan stamp on the side of the M4 blade is a turn off for some...but if you are seeking performance, you will quickly learn to overlook these letters on the blade (truth is, great knives can come from anywhere that skilled builders have access to fantastic materials...but not everyone is ready to carry a knife that from some countries of origin). No right, no wrong, just reality.
