Yeah, it's hit or miss. Some timing chains simply won't go the distance, and then they tend to be harder to change. A TB job means one tends to get a new WP and thermostat, and then the engine never deals with worn guides or whatever. If it wasn't such a pain on traverse engines I'd lean towards the TB.
Not sure how Honda rates on it the job, from what I've seen and read, it's not bad--except for the crank bolt, which needs a stout impact and a special socket as the bolt tends to need 8 bajillion foot-pounds to break it loose. Mechanics seem to think nothing of this job but then again, if I did something once or twice a week I'd probably think it easy-peasy too.
Oh: adjusting valves should be thought about too.
