Opinion on pros and cons of chainsaw chain

[Swift1230]

Newbie here. Thanks for the add to your site. I have owned a couple Stihl saws in the past. I just purchased my first Husqvarna 450 rancher with the 20" bar and the sp33g nk chain. I'm looking to upgrade the chain to something a little more aggressive. It is the 80dl .325 .050. I'm looking at either going with the Oregon M80, or the Oregon 20lpx080g. The 80 has the flat chisel, and the 201 has the rounded chisel teeth ...or maybe the other way around....Just wondering what your thoughts were. Id rather just change chains than the bar also. Thanks.

Hmm, that's interesting. I ran the LPX chain for years and sharpened it either as stock or with a square corner (full square chisel) over that period. Cut like a bandit with that full square chisel but learning how to file it took some time with a 6 corner file. When the new X-cut chain came out I tried it and fell in love. Easier to sharpen, no stretch, and cut great out of the box. It's all I use now and I cut a fair amount. I still have my LPX chains, but really don't run them because they don't give me the consistent good chips I can get off a X-cut. I cant comment much on the M80, I only had one and marked the box 'do not buy again', but I don't recall why. 
 Not sure why you are anxious to dump the X-cut, it's a good chain. What are you cutting? How much do you cut?

Not knocking you, but it's not the chain it's more the saw. My wife 😆 runs a 555XP and even that didn't wake up till we put good skiptooth chain on it.

. Usually it's oaks and maple with the occasional few pines. Maybe 8 hours a year or so.

SP33G would be one of my first choices in that size chain, if you have the bar to match it.

The single best thing you can do to improve performance is learn to sharpen your own chain. Husqvarna makes one of their roller file guides specifically to work with that size chain. With a few pointers and a little practice, you can easily match or beat new out-of-the box performance.
