I agree with the majority of posts here - the extensions that WA produce are great. However, there are always teething troubles when they release a new one, and Data Bridge seems to contain a lot of bugs - from reading the issues others are having, which is why I haven't upgraded yet.
I can also say that WA do issues fixes and these do correct the problems. I too bought Super Suite back in 2007 I believe it was and have been using the extensions it provides for lots of different web projects ever since, covering everything from super basic 2 page sites through to complex database driven sites with a custom built CMS solution that integrates directly with my client's Sage CRM system.
I've also called on WA for support lots of times and found them to be super helpful and always able to fix the issues I was having. Jason has called me. free of charge to fix errors and I live in the UK!
I'll be sticking with WA products and would recommend them to others.
p.s. Form Builder really does need neater code though - sorry, I had to say it I hate the way it uses unordered lists to produce forms.
