For home domestic work I would use a product called Mitox which is distributed in the UK.
It is chinese production but build quality controlled by an English company. Reliable and full parts and warranty back up.
We might not like chinese production but all manufacturers are doing it.
Stihl are big in china for assembly.
Professional I would choose Husqvarna, Efco (Emak) or Stihl.
Kawasaki an option but very expensive over here.
Each manufacturer has good machines for different applications.
Husqvarna for small saws, Stihl for big saws and Emak do good machines but mostly for the 2 stroke engines
