Epic offers jack shit in terms of features, has admitted to be losing money from the 12% cut, has a shitty storefront and is beholden to Tencent, the shittiest gaming company known to the world. Also, Steam is free advertisement, whereas the EGS is antiadvertisement.

There's at least as much of a "massive discrepancy" between what Valve and Epic provide as value to people that chose their service.
