A vehicle with leaf spring suspension is not as comfortable as a coil sprung vehicle. The most comfortable and capable offroad suspension setup I have found is live axle front and rear with coil springs all round.
The navaras have a live axle rear with leaf springs and Independent Front suspension with torsion bars.
If you want a dual cab ute designed for the bitumen road with good offroad capabilites get a navara. If you want a vehicle designed for offroad use with some bitumen road capabilities get a short wheel base live axle coil sprung vehicle e.g Patrol Shorty or Jeep wrangler.
Offroad the navaras are capable especially with a 2" lift. I used to have a lifted coil sprung vehicle that was amazing offroad, however I spent less then 1% of my driving time offroad so my priorities have shifted to on road handling, fuel economy, and packing space (the tray).
You need to decide what you want to do with your 4x4, if you want to do difficult offroad tracks every weekend with your mates in patrols, cruisers, wranglers etc I would consider something else.
