Well, CH can do 71 commands (3x24-1) on both throttle and stick each
(143 in total, as you only need one mode switch button). Talk about unprecedented.
Not that I find use for the mode switch in most cases, 48 controls in total (not counting axes) is more than enough for just about every game out there. The theoretical maximum is 188 independent bindings on the entire HOTAS (8x24-4, you have four modes and two controllers, minus one HAT for the selector), but that requires scripting. And that's not even mentioning axes, of which there are 3 per controller and which are also mode-switchable (giving you 27 axes if you're using the pedals, or even 36 if you're using the scripted modes). Oh, and each axis can be turned into three buttons (deflect positive, deflect negative, center).
Really, perhaps the bes thing about CH is the Control Manager. Sure, it can be annoying at times, but it's really powerful.
But in general what made me consider CH in the first place is that the aestethics of both TM and Saitek make me think of something made more to be flashy rather than functional, I never understood the LEDs in particular. I get the one on the CH Throttle but the decorative ones make me always think that they might have used the money for the LEDs to make everything else a bit more sturdy.
Yeah, one thing I like about CH stuff is that it's got a very "no-nonsense" feeling. Their controllers are designed using the same tenets as actual aircraft controls rather than the usual approach to gaming controllers (seeing as CH is more known for the former than the latter, it's hardly surprising) and the switches probably come off the same assembly line as ones meant for aircraft and industrial equipment. You can even order replacement parts from the industrial catalog, not that you'd ever need to.
Other sticks often have tons of blinkenlights and decidedly odd layout decisions that seem to serve aesthetics more than usability (though I never really used a Saitek joystick, so I don't know how they feel). CH gives you a single mode indicator diode and a very ergonomic layout that puts every button right under your fingers.
