I'm not trying to be like LA just wondering if there could be benefit from always climbing out of the saddle.
Climbing out of the saddle takes more energy than climbing seated, for a given speed. If you are standing, you are also supporting your weight. So, in general, it's better to climb seated.
The riders that you are seeing standing up now and then are doing it to stretch their legs and use a slightly different set of muscles. If you want to do that, you should shift up a gear or two, but don't try to climb faster as you will totally blow out of your aerobic zone.
Armstrong - especially in 2001 - had a surplus of aerobic capacity. He was less efficient when he was standing, but he was more powerful, and he had enough extra aerobic capacity to be able to keep it up.
