I have an Anderson Drop Top as my main guitar and a Suhr Pro Series S4 (? not sure of the model number... went to the Suhr website and can't find anything about the Pro Series. Was it discontinued??). Both are great guitars. The neck on the Suhr is a little thicker- more of a D shape.
Currently I have 3 Suhrs, 3 Tylers and 2 Andersons and have owned many more.
It is all in how the guitar is spec`d out.
They are all top notch regarding workmanship.
Most Andersons have thin necks though (TA standard backshape) and I prefer the thicker ones like Tyler`s 59 shape.
So I am selling one of my Andersons because of that (A Floyded Classic that used to belong to Neal Schon) my other TA has a fatter neck that I love.
You can`t go wrong with any of them I think.
