Like 45ACPKING said "there is really no wrong answer for this thread. "
I don't hunt with any detachable magazine rifles at all. My old Ross I got in 1967 has a fixed mag, my first (and only) new rifle (1976), a 243 Remington model 700 has a blind box magazine. My other rifles are all top loaders too, though a couple have hinged floorplates that make unloading easier.
I suppose a magazine may help loading in a hurry if you are road-hunting, but if I see a game animal while driving, I can get out and load two cartridges in through the top fast enough. I can't remember any occasion where I've lost a chance by being too slow doing that. Get out of the truck, extract the rifle, shove two into the magazine, ka-chunk one into the breech, and I'm loaded and ready to shoot. There is always the chance of misplacing the magazine inside the vehicle or having it drop out of the rifle while hunting too. I have seen my friends with detachable mags do that.
