I have not paddled a Midway, but the Disco is lively and fun. It is a paddling boat not a fishing barge. Still I'd be happy to fish from one once it was rigged right.
I also think the Tempo is just an improved Scupper pro.
Unless I was planning to stand and cast most of the time I would be happy with either of these boats. My choice would be the Disco. Fun to paddle and fish.
