I made this same decision last week and I went with the 441. The 460 has more power on paper, but they are both 70cc+ saws, so you probably are not going to notice. What you will notice is how well the anti-vibration system works and how clean the centrifugal air system stays on the 441. Well, technically I guess you won't notice as that is their purpose.
The 441 is no slouch on power. Period. What is even more amazing is that this saw builds the same power as the 440/460 but does so on less fuel. It is an amazingly efficient motor. I noodled 16 big rounds (18-24") yesterday, and it just powered through them. Plus, I still had a 1/4 tank of fuel remaining. This is all being done while the saw is running a little rich and low RPM for the break-in period. I was sitting there scratching my head, b/c at this rate it may take a while to get through the 10-15 tank break-in period whereafter the saw supposedly opens up a bit.
Tried and true? This argument is just not holding water with me. The 441 has been in real guys hands for 3 years now, and there are no major technical bulletins from Stihl on the 441. Stihl is very quick to put out a bulletin when they find their product needs a fix. The 441 is proving its reliability in the field.
Now, if you are hot and heavy for modding, then you should get the 460. If you are gonna run stock, then I see no reason not to pick the 441.
The european Stihl sites are so much better than ours. Check this out:
