Emilia is a good race but Fleche is definitely the more prestigious one as it is part of that Ardennes treble.FW always had a better startlist than Emilia. It is a great WT race and one of the biggest feat in cycling is winning the Ardennes treble.
Italian fall races has always been clustered together with Lombardia being the main attraction.
Fleché still has more stand-alone value despite being part of a "treble" and LBL being the main race.
AGR was at one point seen as close to being a monument, despite SB surpassing that these days and closer to holding that title now.
