It takes a little getting used to, but I think once you've learned the differences you will love the new Web Builder. It still gives you the design freedom, but also adds some nice additions and choices. Having used both, I am very happy with the new Web Builder.
It does take some getting used to. Is there something specific I can help with? I can switch it back to use Sitebuilder if you like, but as Janet said, there are some nice features in the new builder. Let me know if you want to give it a shot, or convert it back to Sitebuilder.
