So the one you have now offers more hood protection than many of the others short of the predator style, as most of the military ones for the GMV trucks focused more on pushing stuff out of the way and keeping the truck moving, not on protecting the fiberglass of the hood.
The W style front bumper is really heavy duty in the middle, but at the ends it's below the level of the turn signals. The Ibistek is about the same, but sticks out further in front of the truck (by about a foot).
Any of the military ones can be used with a winch. The ibistek requires the A2 winch plate (that you have) and the W style can be used with the milemarker plate, and possibly the A2 plate (i got my milemarker winch plate from a guy changing from a W style to the ibistek push bumper)
I don't believe there are any issues with the predator style and winch plates.
The luverne style brush guard certainly is heavier than the one you have now, and would probably offer better protection from head on impact than the tubular style.
If deer are your biggest worry, then the predator D ring brush guard is probably the best overall protection for the front end/hood. It costs a lot, but it's less than a new replacement hood.
