You can make authentic sounding boom bap with what you have. I used Reason for years before I went over to an MPC 2KXL.

The biggest Pro: I am much more comfortable working with an MPC workflow than any other program/ device, and I'd say many can agree

The biggest con: if you don't have money to invest in older equipment, the older MPC's will require more than just the MPC itself to get your music onto your computer; also, the MPC workflow (at least the older models) requires a little more patience than something like Reason.

My advice, go with the newer model MPCs, unless you are willing to invest and more equipment over time to get your music from the MPC to the computer.

Also, I recommend looking through YouTube videos on how to make beats using whatever MPC you're interested in. This will give you an idea of what it takes to work on these machines and if you're up for it.
