In terms of price? F9 Pros are a $40 dollars premium on top of the EDC3s
In terms of sound? F9 Pros are hybrid IEMS (BAs+dyanmic drivers) while EDC3s are BA IEMs. The F9s will definitely have a sound signature that is more V-shaped than the EDC3s, while the EDC3s will sound a lot more netural, flat and less fun. Whichever sounds better depends on your preferred sound signature.
In terms of accessories? F9 Pros come with slightly more accessories than EDC3s. F9 Pros come with 12 sets of eartips, while the EDCs come with 5. Both come with 2 cables, albeit, different kind of cables.
