The most important thing by far is fit.
You can go nuts ordering and returning boots, so find a store that has a good selection to try on. Here in NH, we use Farmway in Bradford VT, the Bootleggers outlets, the Cabela's store in S Portland ME, and others. Once the right fitting boot is found, it can often be ordered cheaper on line.
Make sure your heels do not move side-to-side in the boots when laced, that there is no significant heel lift, and of course, with the wide forefoot, that there is no pinching up front. Sometimes the addition of orthotics, or shaped insoles can tighten things up if needed.
For me, I like the quality as well as fit of Danner 452s for winter use, about a pound heavier per pair than Keen mids; but for you, they might not fit at all.
Once you find boots that fit, then quality can be compared.
