My only issue is that your answer to the OP's question "Which of these Schumann pieces should I play" was "Something by Liszt cause I don't know anything about the choices you are asking about".
I'm pleased that you are warming to Bobby. 
I see.. Well, now that I think of it, that wasn't the best answer I could have given. I probably should have said "let me tell you what I know about one of your other choices."
However, I did not mean to suggest the Dante only because I know it better. From what I do know, all those Schumann works look massive in scale, and all have great difficulties (including awkward piano writing). I feel like the Liszt Dante is a smaller scale work and probably a bit more manageable than some of these other works that are 30 or so minutes long. And the piano writing is not very awkward, as long as you can do some octaves and wade through some chords (that's an oversimplification, but there aren't any spots like the ending of Schumann Fantasy 2nd movement, for example, and it's not as relentless as the Toccata the OP mentioned). And the Symphonic Etudes seem to have some scary variations in them..
Also, Dante compared to the other Schumann options: Liszt B minor? Either Chopin Sonatas? All have staggering difficulties, and in ways, seem (to me) like they pose some greater challenges than the Dante. I'm pretty comfortable with rapid chords and octaves, and the finger work in arpeggio patterns and broken chord patterns are not too terribly awkward or terrifying.
But the OP, good luck with whatever you choose!
