What's the difference in the Joeys?

Ok. First, I remember now about have to get H+ to get J4. Apologies for not remembering.

Now:

Is all of the following correct?

I can go to Solidsignal and get a Joey and self install it (paying rent to fDish every month for it even though I bought it from SS) and get Amazon Prime on it like on a H3.

Or I can get a J4 (rented from Dish) with a Hopper+ (which is free) and then just dump the H+, but have Prime on the H3 and J4.

If I am correct, what do I do with the disconnected H+?
you'll still pay the monthly fee for each joey. it's called a mirror fee vs paying for programming all over again
