Pine Top is the most likely, though near Bush Mountain is what I think are the most impressive views, the drop is not right by the site. The high Guadalupes are amazing beyond description, but the total lack of water combined with the big elevation gains to get there makes them tougher than the high Chisos.
What GUMO lacks is the sheer size and diversity of BIBE. When combined with Lincoln NF and CACA... I mean Carlsbad Caverns..

the area is similarly amazing
