sauerkraut for experimental is further along because it has been released for a bit longer. They also have a few more active core developers, as their patcher has been released/open source from the beginning. Now that Oxide has released Oxide 2 along with the patcher publicly -- I suspect things here will move quickly. Oxide has always had a strong plugin base, once the plugin developers become more familiar with Oxide 2 things will pick up. TL;DR -- Give Oxide 2 more time.
