Also do either brands have a means to drain the gas from the carbeurator.
Most 2-stroke oil have gasoline stablizer but it is better to leave
no gas to gum up the carbeurator

I have to disagree with you on this. I have a 20 year old Stihl
chainsaw. I have NEVER drained the gas out of it. I use the Stihl
oil that has stabilizer in it. I usually use the saw at least a
couple of time a year and ever time I go to start it, it will start
within 3 pulls. I would think draining the gas out would be a pain
and an inconvenience. Also it would dry the gaskets out.
