Jon, the biggest problem with AC is not whether it is run locally or online. The real issue is that we are using a program that was great 15 years ago, less great 5 years ago, and now is well behind the times.
So my answer to "would you switch?" is "how would the program be different"?
Because if it is the same program, it doesn't really make much difference which button I click to run it.
(OK, that is a blunt and over-simplified answer, but it is what I am feeling....).
