My brother sold his 460 after running my ported 462 and got a ported 462. As we get older, the weight difference becomes more important.
Performance wise, it can be a tough call because 046/460 timing #s and performance are all over the place! Some of them run much stronger than others.
But the 462 is much more user friendly. It is smoother, it is faster, it is computer controlled (no tuning) and has instant throttle response. It also has that real nice clean air filter technology, which saves a lot of time with not cleaning the filter so often. The 460 has a few more ccs, and if you got a good one it may have a bit more grunt. With 20" and 24" bars my 462s are my go-to saws, with 28" bars I will usually go with a hybrid or my ported 460.
Note: Almost everything I cut is hardwood.
