Watching a talk from one of the guys that worked on Inbox, they built a lot of what they did on the power of what GMail already has. But their goal was to create a common flow that would handle most people's use-case. From what I've seen of inbox right now, there isn't a lot you can do to customize it. So until they start porting over features from GMail, I'd probably just stick with Priority Inbox if you like it's flow.

For me, Inbox solves my use-case for my personal email account. I never really put much time into organizing my gmail account to minimize noise, so Inbox was a good answer for me. Now, if Inbox was available for my work account I doubt I'd use it. I have carefully crafted lots of labels and filters to make Gmail an excellent solution for work, it just took more time to setup and maintain then what Inbox does for my personal email.
