Depends on the bar that's on it. I have 2 ported 395s. They are amazing saws. Put a 36"+ bar on it and it really impresses (not in a scary way). Put a 24" and an 8 pin on it and it gets quite a bit scarier. Like, make sure you KNOW where the tip is, and have your thumb wrapped around that handlebar. Personally I like the 395 over the 661 for my own reasons, but those may have the edge if you're looking for stock performance, or scariness. They are lighter and with bars under 36" I think they might have a slight edge on the 395. Ported they are very impressive saws.
