I have just retired a pair of Scarpa SLs after 15 years. Upper is still great but the tread is nearly dead. Summer work boots now. I bought another pair (the later model SL M3) recently and they seem just as well made and are a great medium weight boot. They get my vote for durability. They don't have a gortex or other liner like a lot of boots either. Better if river crossing where they are full of water all day. Cooler in summer to.
My Zamberlane Voiz gtx are the mostly comfortable boots I own. Fairly light and fit like a glove. Even after a long day on the hill I don't feel the need to take them off when I get back to the car. A pleasure to wear.
My kick arse/snow/rocks or kick whatever you like boots are my Garmont Pinnacles. Big high rand and very stiff sole. Great in the mountains in winter. I have a pair of Scarpa Mantras which are similar but have only done a couple of trips in them. So far so good though.
