True, this version is harder to configure than previous ones. On the other hand it offers protections and actions that no other product does. Particular attention has been made to not send cookies that can be used to track you in a number of situations that other's don't even try to handle. And machete lets you completely rewrite pages, letting have back those web pages that used to be great and are now full of distraction.
If you've been surfing a lot you've noticed that there are many more ways to invade your eyeballs than the old banner gif. Finally there is a tool that gives you the tools to really control what you see. Ahead of its time - let the new features sink in and mature with practice.
Regarding support - developer response is excellent. If you are having trouble, register for the 10 bucks and send him email. Satisfaction guaranteed.
One point off support/documentation, since although support is outstanding, documentation could be more thorough. One point off ease of use not for lack of effort, but to acknowledge these are new tools and some just take some effort to get your head around and developer needs some experience to figure out how to best present them to users.
