The cam lever is there if you don't want to readjust your tension when you change saw blades. I suppose this would be nice if ou go through a LOT of saw blades. Not worth the extra $18 to me, as I change saw blades every couple of weeks at most.
The swivel is for detailed piercing work. Don't want to/can't turn your work? Turn the blade.

I have the three inch and five inch. Overall, if I were to get used to one one would be fine, but I like being able to use the three inch for intricate saw piercing and the five inch for more basic cuts. I've tried an assortment of blades, and even cheaper blades stand up relatively well compared to traditional frames.

It could be just me, but I find I have more control with the three inch. I like to sit so that I am looking at the saw blade from behind while it is basically aligned with where it is going. The 3" let's me do this without being too far back. When I use the 5 inch I have to be further back or looking from one side (not a huge deal, depending on how much clearance I have, but I find that if I do t look from directly behind the frame, I will angle my cuts a teeny bit).
Can't really say a thin about the cam lever. It wasn't an option when I bought mine. The swivel aspect sounds like it wOuld remove the issues I find with a 5 inch vs 3 inch. I haven't had much issue with blade changes, but I am just happy to not be bruising myself trying to tighten blades on a normal frame.
