Reference the Merril Moab's the reason I got the gtx versions and not those without was cause that was what they had in the shop at the time and fitted extremely well from the off. Yep to the none gtx version would be just as good if not better, with bog jumping your feet are going to get wet through the boots no matter what but as I carry a spare pair of socks in the car no biggie and if necessary I also have gtx sock and seal skins but most of my long distance walks I use anything from sport socks to 1000 mile sock and standard walking socks too, they have great support and are light on your feet compared to leather boots, (which I wear to work though orders not choice ). but for walking they are a lot lighter and 1kg on your feet is the same as having 5kg on your back. the merril's also got a great review in trail think they were best in test although I have had mine ages and will soon be replacing them through wear and probably get a second pair to ease up the damage to them.
