The On One ones were different. I’ve got some Outlands on my Heckler. They’re not super grippy, but ok for me in rocky and rooty terrain with Shimano AM41s. They’ve lasted very well since I started using them just over a year ago; no play and still have all the pins despite fairly regular bashing. The body is slightly convex to accomodate the axle, so comfort might depend on how stiff/thick-soled your shoes are. I’ve not found it to be a problem.
I’ve got Superstar Nanotechs (actually the Carboncycles version) on my other bike and they’re grippier, but the sealing isn’t as good and the bushings are already on their way out after just a couple of months.
Edit: IIRC they’re rebadged (and cheaper) VP59s. There’s a bit more info on them on mtbr.
