Admittedly I've only heard the various YouTube demos and shootouts, but I'd say the tap tempo, longer max delay time and adjustable 'age' on the Dunlop edges it over the Belle Epoch for me. Other than that they both seem to be equally good sounding variations on the theme.
Shame the Belle Epoch Deluxe still doesn't have tap tempo - seems like a bit of a wasted opportunity not to have the second footswitch assignable as either tempo or oscillation. Also seems odd to deliberately limit the delay time if you're doing everything digitally.
