In my experience, the FII is better than the FI. The FI is good, but it wears down way too quickly, and the FII is still in good shape. However, the FII is new, so I don't know if it is durable or not. So I would say get the FII, and only get the FI if you have a lot of extra cash on your hands.
As for the type Cs, they are both excellent. I like the type CI better than the CII, but a lot of people like the CII better.
In my opinion, get them in this order: FII, CI, CII, FI.
