We seem still to be a very long way away from naming and citing 100 such concertos but, who knows, we may well get there (or even beyond) in the end. Perhaps also the thread title might better be amended from "100 romantic concertos superior to the Schumann" to "100 Romantic piano concertos superior to the Schumann", as I feel sure that no one here is seeking to compare Romantic concerti for other instruments with poor old Schumann's aberration (which I cannot help but wonder why he omitted to suppress as, irrespective of how "inferior" it might be to other Romantic piano concertos, it's undoubteldy inferior to most of the remainder of his own work).
OK, no one has yet mentioned the Busoni, Rachmaninov's four, Medtner's three, Brahms's two, the second concertos respectively by Liszt and Tchaikovsky, the two Concerti da Camera by Alkan or even the Dvořák - and these are just fifteen of the better known ones! Then there's the works for piano left hand and orchestra by Strauss and Korngold, the concertos of English composers Ireland, Bowen and (Alan) Bush and perhaps the most obvious choice, given its name - the Romantisches Klavierkonzert by Marx.
Best,
