There seem to be a couple of price points and then people get into arguments within each. The lower price area is between about $200-$300. The high range is typically $400 to a bit over $500. There are countless threads about pros and cons at ADVRider.
Personally, I haven't found a boot that crossed the line well enough between dirt and touring, so I went with two pair. My road-oriented boots are Sidi Way Rains. What I like is that I could get them wide enough, they are incredibly lighter than some other boots I have, and they've kept their waterproofing.
For more dirt oriented riding, but keeping the ability to ride all day on the road, I have a pair of AlpineStar Toucan boots. When I motocrossed and rode desert a lot in the Mojave, I'd occasionally crash with my lower leg between the peg and something hard. Going on 60 now, my leg would never take that abuse. People go on and on about Gaerne and others, but I've not found anything else short of a motocross boot that is as good as the Toucan for protecting against a foot peg impalement and for calf protection. Plus, with the hinged ankle I can't over-extend the toe. For road riding they are incredibly comfortable, the sole is replaceable, and they are surprisingly light. The only quirk I've found is that they occasionally need a little silicone oil when the hinge starts to squeak.
Again, there are LOTS of really good boots and you're going to get people's favorites just like an oil thread. This is one of those topics where you need to see what is comfy and gives the protection important to you personally.
