I have a roughly twenty-year-old coffee-table book about commercial aircraft, and one section of the book dealt with both propfans and ultra-high-bypass versions of traditional ducted turbofans. The propfan got much more attention in the book, as I'm sure it did in real-life aviation industry circles, but the writers managed to include one photo of an experimental UHB ducted turbofan engine (a Rolls-Royce project called the ContraFan, I believe) and a side-profile diagram for a UHB ducted turbofan engine right below a similar one for a propfan engine.
Frankly, IMO, based on both the photo and the diagram, the UHB ducted turbofans under development back in the mid 1980s would have been rather awkward, inelegant, and just plain ugly in layout, particularly since those engines were slated to have the same "pusher" fan configurations as the propfans then being devised for such stillborn aircraft as the Boeing 7J7 and the McDonnell-Douglas MD
-92X, and MD
-94X. FWIW, however, the authors of that book believed that UHB ducted turbofans would have had at least one edge over propfans; the authors thought that UHB ducted turbofans were better suited to longhaul aircraft than were propfans.
I may question your opinion, but I'll never question your right to it.
