I pretty much just use the Hercules stands as well, and I do still like them best, but I have had some issues with them...
In a couple cases, somehow, the mechanism kinda' got out of sync, which can be "fixed" by snapping one of the tips back to where it's supposed to go, but a couple times and it just stops working right in general. I could probably handle the stand a bit more carefully in the future, but sometimes loading in/out you get in a hurry, weather, etc, and you tend to toss stuff a little. Stands without mechanisms like this won't have this problem.
The other issue I've had is how most of their models are more of a square cage with relatively thin and specifically located pads, rather than just a coated yoke. What that means is certain headstock shapes/sizes will cause the bass to be a little off kilter and you could actually end up with hard plastic contact against wood. Just being careful getting the bass in/out minimizes risk of marring, but there is some risk nonetheless.
Overall, both are low probability low risk issues, but just to say as good as they are, they aren't perfect, either.
Ideally, I'd love to see more of their stands with that "universal" (yoke) system up top, but one that folds up. If you think about it, if a more gripping mech needed, the bass/stand are already falling forward and you have bigger issues than worrying if the neck comes out of the holder or not.
