Merrills are comfy out of the box because they're just a step above WalMart brand running shoes these days. (read: they're pretty crappy actually and their brand recognition is from models of years past)
Danners are stiff because they're quality and require a break-in. Asolo as well. Asolo also tends to run narrow.
Salomons are probably the best mix between the two. Personally I prefer Salomon 4D because they're surprisingly sturdy, they have fantastic grip, a really wide toe box, and they're light. You're also getting into top tier prices with the 4D line.

Where are you having issues? Like physically on your foot, what part is causing trouble? What kind of socks are you wearing? My boots feel like shit if I wear running socks in them. They feel incredible if I wear hiking socks.
Other brands I'd look into:
Keen (nice wide toe box)
Vasque (built for comfort, but better quality than the shit show Merrill has been putting out for the last few years)
Try Lowa too
