Well I dont throw my opinion in very often. I have been offroad jeeping since I was 14. Bought my first jeep at that age and am 50 now. I have owned and built, modified 13 jeeps for off road use. I have been part of jeep offroad clubs. I agree with both sides of the arguement but not to the original poster. After all the years I have seen too many newbies wreck their rigs and the environment because they put lockers in and thought they are king offroaders. Lockers will get you into trouble if you do not have the experience to use them. In snow and especially ice they will spit you off the road because both tires are spinning. Trust me I have been there and had it happen. I have ridden jeeps off the side of mountain forest service roads and spent days winching them out. Do i think lockers are good to have and a smart purchase. Absolutely but not for newbies without experience. And not on the front end only. In the jeep world a lot of people modify the jeeps to be able to engage the front dif and front locker only disengaging the rear end so they can pull themselves around a obstacle. I have seen a lot of blown up front diffs and have been on the rescue crew to go in with another diff to install and get the rig back out. Lockers are hard on front ends and components. My advise to anyone with any level of experience is to first purchase good recovery gear and good tires before anything. Good recovery gear means a winch, straps, tree savers, bubba wrope, shackles, gloves, etc. And learn how to properly use them and maintenance them.
Either choice you make is great. Stay safe and dont subject other people to stupid decisions without proper gear.
