I center punched a doe last September running away from me at 20 mph ( I guess - I had time to lock up the brakes. ) It destroyed the grill, concaved the condensor, and shoved the radiator into the fan clutch, which cut a nice doughnut in my all brass three core.
A frickin 100 pound deer - again, running down the road the same direction. You got off lucky. I'm looking for a bumper like what you have to help minimize any future repeats.
Stick with what you know will work. A stiffer bumper will total the front end and then the Jeep will be toast - or you will be. Are you running a five point racing harness? Whatever, replace it. Just like a helmet, seatbelts are only good for one hit.
Fer instance: the McAlester Army Ammunition Plant let their elk restocking program literally die off when Security kept totaling their 4WD patrol trucks in nighttime collisions. The elk tended to use the roadways at night for trails, and an 1100 pound animal getting hit over 30 mph tends to shove the engine under the floor a little - which is exactly how Detroit designed it. Better than in your lap.
Successful offroader's learn the dynamics and stay on top of the dirt - not six feet under.
