These aren't for everyone, some players find them too sensitive. But if they're the right button for you, not even the OBSF-30 comes close!
The matte texture means you'll feel it if you're pushing it just by brushing - so you can learn to do it when you mean to for a little extra speed and precision as you move between buttons, instead of by accident when it'll drop a combo. You don't have to push as far to engage as most buttons, and it takes less force than the similar Seimitsu PS-15.
So if they suit you, there's nothing else like it and the only downsides are the lack of colour options and the limited stock out there. If you need to give them a go first, borrow someone's stick using them (recent Hori sticks or something modded) or buy one or two to get a feel for 'em.
