Any Nissan mechanics onboard?

They went from gears and chains to belt drives, a good thing for the motor trade, as cars became more reliable and service times extended, we had the cambelt to keep us going for years and years. If not replacements then fixing the fuckup when it broke - thank you vehicle manufacturers. So now we have chains - uh oh, there goes our cash cow. But no, these things seem to last only a few thousand more km than a belt, and there is a shit load more work and costs involved in doing it. The Holden 3.6 V6 is a good example, what a fuckup - roller chain or morse, they both wear out.

Here is a Holden we did last year that was one key start away from catastrophe.

I much prefer belts, most of the ones I have done have been straight forward. Just downloaded a manual for the yd25, and the only bit that is missing is the section on timing chains.

I prefer gears that last forever, or a chain that lasts the life of an engine - why build in huge maintenance costs over the lifetime of an vehicle?

Nothing it seems, is built to last for any great length of time these days. Thats why I prefer older cars myself, the newer stuff seems to wear out rather quickly.
This Navara has less than 100,000kms and the fuel timing chain is shagged already, not good enough for my liking.

Unlike the fibre timing gears on Holdens

Mainly a problem on that stupid Starfire engine, they used to chew up the fibre gear, and you couldn't fir an alloy one. Most red engines were reringed or reconditioned and the old gear reused. Worked on red engines for years and only did a couple of cam gears - we did them in the car, didn't pull the cam out. Did more Starfire cam gears than 6 cyl.

I did one on a HT 161 and a HQ 173 and plenty of others I knew did them as well, bought an alloy set from Repco off the shelf and did it in the driveway

I was probably working on them when they were newer and came to a garage for repair, not done as a home job. Still, they lasted a shit load longer than a chain does in a 3.6.
