Couldn't hope to advise which one of the two saws to get with the amount of information provided regarding the intended usage.
Why not?
It's not like the 2 choices were 088 and 017!
You cut firewood and limb with both of them. Neither will go out and cut down redwoods. Neither are big time pro saws, built to last forever and pull 42" bars. just basic homeowner saws. small woodlot stuff to me means limbs, and occasional smaller tree. Either will work, but for close to the same $$$, I'll go 039 every time.
I don't get why you need to know exact diameters, and species, hot or cold weather, chain pitch an all that.
ms280 3.31ci, 3.6hp16-20"bar
ms390 3.9ci, 4.3hp16-28" bar
that stihl published figures, both listed as mid-range saws.
I personally wouldn't go over 18" b&c on the 28, running .325 pitch
and wouldn't go over 20" b&c on the 39, running 3/8
