[Best MitM attacks nowadays?]

I bought a pineapple and want to impress people I know but there's so many options its crazy. I used to use yamas and it seems like it still might be the best solution to just run yamas on a laptop insteasd of having the pineapple :/ but I also have raspberry pi I can use with the pineapple. Also sslstrip for the pineapple is very wierd and I'd like to see the source code how is that possible?
