The h48 is very similar to oregon 73lgx. The rakers appear identical in shape. But the cutter is slightly smaller on the husky chain.
View attachment 293135 I find lgx has a longer life, better chip clearance and more durability because of the larger cutter. Not by much. But the difference is there. As far as what one cuts faster out of the box... I have not tested that aspect. Out of the box performance doesn’t really satisfy me with either one. I change all that after I file it anyway and tune the chain to the saw it is on. I prefer EXL or RS chain performance out of the box over 73lgx, H48 and C85 chains. They seem hold a edge better as well.
