I would say if you like the vitals , give em a try.
as with any product you will find some who love it and some who hate it.
I where my pronghorns every day and am tough on them so I seldom get more then a year or two at best out of them. that may not sound great but I have found no other boot that holds up any better .and that includes kenetrek. my kenetreks was a fine boot but I simply could not justify paying twice the price of a danner a second time, when they held up no longer.
I can't speak to warranties comparison ,because as I said , I am hard on boots and figure it is wrong to take unreasonable advantage of a company.
as with all boots fit is key to comfort.
IMO ,danner makes a solid product and price is reasonable.
