As always these POS threads have more BS in them than a bull's intestinal tract. I see nothing new here at all. The FACTS have been given many, many times before. The 261 and 346 NE or OE are both stronger than the 5100, end of story. This is fact not hearsay. Same thing with the 261 vs the 346, the 261 IS stronger than the 346. With that all said, run what you like and stop making useless threads like this, they all cut wood.
Although some may be pushing an agenda with their favorite brand, it seems like many are just expressing their opinions on the subject. You may or may not consider them valid. Defining the "best saw" by how fast they cut cookies in your backyard might be one measure of best. For others, maybe it is not. Considering the minor differences in these saws, and the number of variables involved, your use of the terms "FACTS" or "stronger" seem fairly subjective.
IMO (just an opinion), the performance differences between the 346NE and 5100 are very, very minor. To me, the 5100 has a very slight torque advantage to the 346NE, in my case both with 20" bars and 3/8 chain. The 346OE, while it cuts like a light saber, bogs quicker when buried than the other two. This is not surprising since it has 5cc's less displacement. In my opinion, the OE is not quite as good as an all around saw, however as a limbing saw I think it has no peer.
As I stated, I cannot speak to the 261 (yet:silly

While it is tiring to hear the cheerleaders with their favorite brands drone on relentlessly regardless of the topic, I just overlook those posts and try to learn what I can from the rest.
