Well its more certainly not something you want if you don't need them but, for some its unavoidable. Steel toes have come a long ways.. Especially since Keen has started making steel toes.
carolinas (185-200+)
wolverine (145-160)
red wing (180-200)
keen (135-150)
these are the favorite boots i've used. i definitely got a good run out of the carolinas, they lasted nearly a year and a half when a normal pair only runs about 8-12 months at the most where i was working. they had a definite comfort to them. great boots.
the wolverines were close in comfort as well, they never got too loose to cause problems, were great all the time until i wore them to the point of needing new after 9 months, but it happens. still have them because i plan to use them for other purposes, just not for work anymore, don't need wet feet at work because of worn holes in the leather.
the redwings were very durable, good, but definitely had a different sole and even with a good insert were causing problems for my feet (others feet may be different, but i didnt need a new sole for any of the other boots, just these, and the sole didn't even help). they sit, waiting for a quality sole because i just can't wear them all day because of the fit on my feet.
and the keens i took a shot at, i don't get as much leeway in purchasing boots now that im with a new company so i took a shot at a cheaper boot. but they feel great, can say i'm glad i got them, compared to a full on leather boot they look cheap but they definitely aren't. only complaint i had was the insole didn't last me 2 months before i went back to haney shoes (awesome local shoe store) to get a new insole because these felt great at first, but the insole they came with didn't last worth squat.... with a 20 dollar purchase on new soles i was set and so far it's been great. worth the money, but we will see as i haven't put too much time on them yet to call them as good as the carolinas.
i would rate the carolinas first, then keen, then wolverine, and then the redwing for comfort. and for durability, i would put carolinas on top, then redwing, then wolvering, and i cant say anything about the keen yet.
to Shoefitsu, if you are indeed well endowed with shoe knowledge, i'd like a good method of cleaning grease, black staining, oil staining, etc out of a boot leather. i've tried all kinds of things but still end up having the leather leave marks behind when touching them after they dry, the boots have been through hell but there has to be a way to get them cleaned up again.
