The drive links have the smallest stress area, therefore, are the weakest part. Tie links are doubled up (could also be a toothed link).
Some chains have oil cavities/features stamped in to the drive links themselves (Stihl has marketed this for a long time, but most all of the manufacturers do something similar nowadays). It makes a difference if you have an adjustable oiler and crank it up. Good bar oil makes a bigger difference honestly, as the sticky oil holds to the bar/chain a lot better than just a high viscosity oil alone.
I logged for a few years and ran a saw 10-12 hours a day. Different areas demand different tactics, just like shooting. Some places I used a good sticky oil at a low/mid output setting, other places were so sandy/silty, I'd run less sticky, thinner oil, cranked up to keep it out of my bar, and some places required vegetable based oils, which meant we were using the cheapest decent bar and chain we could find, cause it was going to get destroyed regardless... If you have to run veg based oil, keep a replaceable sprocket bar on your saw, and carry a sprocket greaser with you, otherwise, you'll toast them in no time!
