Quality is the same as the RB2 Ti. Problem with RB3 is that is titanium coated in gold, making it much lighter than the steel versions.
If you've ever held a gold watch in the hand, holding an RB3, you will know immediately that something is off, this is slightly less obvious when holding a steel watch coated in gold.
Also, the back logo is slightly different, it is matt PVD steel, where as the gen is glossy mirror ceramic.
Other things to note are that like the RB2, the plate underneath the dial is completely different.
Personally I'd wait till they fix the case back.
