There is a free 30 day trial of WB so you can check it out yourself.

Obviously these are the Stardock forums so we will be biased, but no, there isn't anything else like WB that can give you custom frames and custom titlebar positions.

I am unsure on your specific question about tab controls as thats purely a skin design choice so the right skin should look like Windows Vista for those areas too.

If you want a skinned start menu you would need to use Start11 however as WindowBlinds will provide skinning support for the Win7 style menu in Start11.
