Plus Americans rather dumb when it comes to mixing fuel with oil. Plus our EPA is frowning on 2 cycles. This why they are being con into buying premix fuels that are up to 4X the cost of fuel/oil done in house. That is why I sell a multi mix oil for gallon containers.
Personally I rather have a good 2 cycle any day over a 4 cycle engine. With that there are a few good 4 cycle engines in the handheld line up that are very good but I still prefer the Stihl 4 mix version over them. My next choice is a diesel as they have just as long of life as most two cycle engines.
I send a lot of the 4 cycle handhelds to the recyclers early. Maybe they get a year of use before they croak.
