I usually like the Anderton's stuff by Jack, he might be playing the role of an easily excited goof, but it works out fine a lot of the time and usually the gear sounds good in those vids. That UB-Xa video was just weird, for someone who is usually super into everything, he didn't seem into it at all and it sounded really bad. Even the earlier quick demos from months ago by some beta testers sounded way better.
There's plenty to hate about Behringer, but I doubt they'd drop the ball so completely, most of their synths sound quite good. Whether or not they'll 100% nail the vintage
OB-Xa tone will be up for debate no matter how bad or good the final product ends up being, but I really expect it to sound OK at worst and excellent at best.
