husky is bar far the best for big.stihl is the top choice for small.
Not by far by a long shot. I have 2 3120's, one is fully woods modded..and a great saw. But, general consensus is the 880 is better. And I am now on my third 066/660...all dual port mufflers. Many say the 395 is a tad faster, stock or modded, but it is also a fair bit heavier. 046 and 044 are great saws, but I prefer the 372 and 7900 Dolmar.
the 440/044, 046/460 are the largest selling logging saws by a huge margin, at least out west. Reliable, long lasting saws for sure.
all this brand loyalty BS...I like them all.
