The latest obsd version (6.6, or the one just before, 6.5) makes package updates easier without running -current. So it probably depends on if that maintainer has kept them current during the release period. I haven't followed that closely to know how much that has been the case.

But see my comments elsewhere in this discussion page for why I value obsd's pledge/unveil browser mods and lack of privilege escalation more important than having the latest browser fixes (which I also value, but relatively less).
