I haven't used Osmo, but I've used Rubio Natural on several recent baltic birch projects. A desk, small cabinet, and 10 kitchen drawer boxes. Application is easy, squeegee on, buff with pad, wipe off excess. Cures in 5 or so days.
I used Natural as it kept the wood closer to its native color, adding slightly yellow tones. I tested the Pure but it was more of an orange tone, however Pure looks great with darker woods such as walnut (Natural has white and will lighten darker wood).
As for wear, I've noticed the desktop is much smoother where I use the mouse, but I think that would happen with any surface/finish. Otherwise, all the projects still look fresh.
Stumpy Nubs recently released a video where he uses boiled linseed oil coated with paste wax and achieved similar results at a much lower price. Rubio is also made with BLO.
