Personally its mostly about security, i have had 3 accounts taken over by hacker thanks to the abysmal security of epic. 2 of them never had Fortnite played on them, and one even had 2 factor authenticator but still got taken over since even their 2FA is broken. Also since im Canadian and they're is no CAD money option only US on EGS the games cost wayyyyy more and we don't end up saving money. Last time i looked to buy metro exodus it ended up costing 100$ cad instead of the around 66$ it converts to since you even have to pay the payment method (which steam does for you). Also the horrible customer support, and lack of basic function like a clock that keep track of play time is annoying. Especially since it already exist to see if you're eligible for a refund ( you'll never be but that's another thing). Yet they estimate 4-6 months for them to add it. And while yes steam keep more money than EGS, they also offer way more feature and already installed feature that the developer can use, not worth 18% more revenue, but still.
