The current is higher, and the voltage lower, at the speaker output terminals compared with the tube connections. That means resistance of the contact is doubly important. There's a reasonable theory, anyhow.
In practical terms, Jeff says "bananas are for test instruments". In my system, I'm always changing things so I regard any amp as a piece of test gear, and I use bananas all the time. They've never given my any difficulties; a small screwdriver can easily restore work contact springs. All my audio buddies use spades, but I just sit back and chuckle to myself watching them struggle and curse. I use $1 interconnects and 20 gauge zipcord speaker wire for the same reasons. Only on rare occasions do I convince myself I'm going to leave something connected permanently, and spend the time and effort to use good connections and good wires.
In case anyone wonders, I do hear the difference and I'd love to have a full set of, say, Shunyata Research cables. But it's not important enough for me to make my life miserable every time I swap out a component. YMMV. :^)
