My experience is with an old, tiny, and heavily used bandsaw mill.
It was on at least its second motor when I bought it, as this one has labeling from a pressure washer. The exhaust manifold bolts studs sheered off in use the other day, so now I need to drill those out and retap, or replace the motor. Everything is worn, or outright broken.
That said, I am glad to have it, and really can't imagine using a chainsaw mill for much milling.
I have a couple hundred acres, but it was thoroughly logged over the last decade.
The very few remaining usable trees, I would prefer to leave alone... but if they are clearly dying, I take them down and use the wood. This is unfortunately quite a few of the few.
The kerf on my bandsaw is very, very thin compared to a chainsaw. I would guess I get an extra board out of every medium sized log I mill, vs a chainsaw.
And, if you consider that you are spending the energy to cut all that kerf, it seems to me I must be using quite a bit less fuel than a chainsaw, cutting the same wood.
Yes, sharpening is an issue. I got a sharpening rig with my mill, but unsurprisingly it is in need of repair. Even so, I have heard you may only get one sharpening out of a blade.
I can have my blades resharpened professionally for about 20 bucks. They cost about 40. Cheaper than a chain. Cutting fir and cedar, they do a fair bit of work before needing sharpening.
I have ripped a couple skids freehand with chainsaws, equipped with brand new purpose-built ripping chains. Fir and western red cedar, the same as what I am milling.
It was brutal for the saw, even a 394XP was working hard, and it did not go quickly. A chainsaw mill would no doubt help immensely vs freehand, but still.
Where would a chainsaw mill be good? If you want to cut big timbers, just one or two per log, much of the kerf is going to be slabwood. No big deal to make more of that into sawdust. And with far less cuts per log vs making boards, a bit more fuel burned is less painful.
Portability... well, I can take my mill whereever the tractor can carry it. It used to have an axle, towing it would be the way to go if I had no tractor, or wanted to take it back in the woods.
I prefer to move the wood to the mill in chunks sized for milling; then, the finished product is all in one place.
