Recommending a chainsaw for someone else is difficult. Which is best for you depends on what you want to do with it, your physical strength and as always your chainsaw experience. Mostly any of the Stihls or Husqvarners (Husky) are good. Still though even high quality companies can come out with a dud model once in a while so when new models come out there is always that chance. I have three Huskys that I use a lot and find them all good for what I use them for.
My oldest husky is a 372 XPG (XP desinates professional model, G designates heated handle). It is the most powerful saw I have ever owned. It flat out eats the tree and bore cuts with ease. At one time I used it exclusively and had two of them. Today at 67 years young, I am not as strong as even five years ago and find the 372 xp to be a bit heavy at 14.3 pounds now. I still use it regularly but especially for cutting up large logs into fire wood lengths.
My second saw is a 562 xp. It is a great saw and even at 13.23 pounds it feels significantly lighter than the 372 XPG. I use it for all around use, felling large trees, cutting up logs, plunge cutting, low hinge cutting, etc. Like Weezy stated; it is a very powerful saw. I wouldn’t hesitate to buy another if I needed one. The 562XP has taken over as my main saw.
My third saw is a 543 XP. It is a smaller saw weighing at 9. 92 lbs. I bought it for light work like releasing apple trees, cutting smaller stems and working in tight areas, and high hinge cutting. Either of the other two saws were simply too heavy for me to hold up “safely” to high hinge cut with. Sometimes in releasing apple trees a high hinge cut is warranted to sort of store the cut trees high in the air to give the deer room to walk.The 543XP is comfortable to hold up for higher hinge cuts. I don’t have the high number of hours on the 543XP as the other two but so far it has been a good saw.
If I were buying a new saw today I wouldn’t hesitate to buy any of the three that would meet my use and strength as they are all very well made. I would also research the 550XP. The description of it reads very well but I have not owned one yet. I have had Stihl and in fact still have a 020T. It is a small climbing saw and is used only very occasionally because of its specialized design.
Within those models one could choose different/multiple bar lengths and different chain styles of course.
