I use the MS store for MS software. But avoid Steam if I can as well as they also take a substantial cut (Although this does mean I still get a lot through steam).
Although they're more flexible, if a game sells you a CD-key outside the store (eg on Humble, through promotions, etc) they don't take a cut. Steam only gets it when it's through the Steam store.
