This couldn't be more true.
There isn't really a huge difference between those. The biggest concern is failure of the twist locking mechanism. I went through a couple pairs of cheap poles that broke because of the twisting lock. The cost isn't a big deal, but losing a pole with 50 lbs on your back out in the wilderness while trying to go up and down 4,000 ft sucks.
Black Diamond came out with flick locks several years ago - simpler and much less prone to failure. I do a ton of hiking and mountaineering and 90% (no exaggeration) of the people I see have the Black Diamond poles. In fact I'm starting to see skiers use them at the slopes now. They are more expensive though.
Now other companies are copying the Black Diamond locking mechanism. However, based on the good Amazon reviews I would give those poles a try, depending on what you do. If you do backpacking on longer trips with heavier loads, I would spend more on something less prone to failure.
