I have run ARBs for a long time and I am happy with them. I have run with a couple people with Ox's. They seem to have to play around with things to get them un locked. I t may have been how they routed the cable, not sure.
Both seem to work really well, I think the installation itself what is the most important. I would find who I trust to do the work and ask them what they are most familiar with.
