If its within budget... I would opt for a resi with external adjusters...
If I didn't, I would end up just being curious about what it would have felt like anyways and would feel I missed out on any potential fine tuning not having the adjusters.
I think this is probably even more important on a multi-use rig... and you will probably develop a preference overtime and for different terrains.
Suspension is also one of those items that you can grow into, and even if you dont, you have some additional headroom when off-road which can play into a saftey/performance argument.
