I have 6 sets of wheels handbuilt with Miche Primato Syntesi hubs, 3 pawl freehubs. Oldest set is about 7 years old, 4 sets between 3 and 5 years old, and 1 set less than 2 years old but very low mileage (less than 1000 miles). The 5 older sets have a cumulative mileage of approx 60K and other than bearing replacement (once on the older hubs iirc) the Miche hubs never had any failures of any type. Freehubs are soft aluminium but if torqued correctly, not a real problem. I do check them over once a year.
That being said, Shimano 600 tricolor (6402) hubs are my favourite. Absolutely love the soft metallic freehub sound on those and the slim and elegant polished hub shells. Not a fan of the chainsaw sounding hubs.
