I see a lot of hiking boots/ shoes between myself and my co-workers. A couple of things I've noticed as some general thoughts regarding the various brands... Very general.
Keens, wear hard, last long, but they have a very hard sole, and that can cause traction problems on rocks, wet surfaces.
Merrels, very soft soles, great traction, but no where near the overall durability.
Solomons, Generally very good quality, but they don't break in. If they start out with pinch points, they keep them. Durability can be a miss as well, I know a few guys that had them come apart within weeks, but that can happen with any shoe. I know others who have gotten a couple years of daily use.
Fit is important, socks more so. That combo is a make or break in most cases. I find the toes in my Merrels a touch narrow, but they do alright.
I personally have been wearing Doc Martin Combs nylon. Odd choice, but as close as I could get to a jungle boot without spending a mint. solid sole, breaths pretty well, and they have held up quite well. I also have a pair of merrel moabs without gore-tex. It comes right down to your useage, I'd rather a boot that dries quick, you may prefer keeping them dry to begin with.
I have co-workers who do half their walking in elastic side blundstones if the track is level, or crocks if the going is wet and sandy. The main thing is to keep in mind that if you push hard on a different pair of shoes, even if they are broke in, your muscles may not like it much, stuff like heel angle and arch can make a huge difference over a couple of days in shoes that your feet have been out of for a while.... just did that. Feet were fine, calves killed me for two days.
