Lamas used to be one of the best. I still think that they are a good boot but they are more "mainstream" and you really need to try them on. Each boot will be a bit different and -- obviously -- everyone's feet are different. Lama (El Paso), Leddy (San Angelo), and Lucchese (San Antonio) were the premiere bootmakers in Texas -- all got their start making boots for Army officers and NCOs.
I think that there are better bootmakers out there than Lama but there are definitely worse. Considering the price of "off the shelf" boots, you might seriously consider getting a good custom bootmaker to make you a pair. Boots are fit and worn a bit different than shoes and if you don't get a corret fit, they can really mess your feet up.
Having said that, I have Lamas in my closet -- one calf and one elephant. The elephant I got as a Christmas gift in about 1972 and they still look like they are only a couple of years old. They are hell to break in but they last forever. My favorite Lama is lizzard. I've had several pair. They breathe, conform to your feet well, and look very good. If I was going to buy an "off the rack" pair of boots, I'd go back to the Lama lizzards.
