It's actually somewhere in-between.

It has an 'unlimited' stack, so a bit like RPL...

Almost. Prime's RPN stack is limited to 128 levels (just like Prime's two other history stacks). When the RPN stack is full and something new is pushed onto the stack, the top level is lost, just like traditional RPN. But like RPL, when anything is dropped, the size of the stack shrinks instead of replicating the top level.

Similar to RPL, Prime's RPN does support lists and other non-numeric values:

{ 1 2 3 } Enter 2 * --> { 2 4 6 }
"ha" Enter Enter + --> "haha"
(Like RPL, the first Enter terminates the command line, and the second Enter performs a DUP)
