i'd like to hear the answer to this as well.
i've tried autopilot in the past and liked it. Automate and WinTask seem quite powerful.
primalscript is really for writing full scripts as in javascript, vb, etc.
my experience is that there isn't much of an overlap in the application of these tools beyond that that both talk about working with "scripts". if you want to write a mini program, as a programmer, then primalscript is good. but for automating stuff without having to sit in front of a book for a few hours to learn how to do something with vbs or javascript, then these automation tools are the way to go.
if anyone feels like they are competent to do a serious review of scripting/automation tools, i'd love to sign you up for a guest review; not going to be an easy review since there are some deep features to explore and several serious contenders, but it would be a great review to have. you'd definitely get a reward of one of the screencasting tools
