Well, a Switch is a great decision and will offer you great gaming experiences. But one thing: if you are disappointed by Sonys networking services, than Nintendo isn't better. There are many reasons for Nintendo, but their online services ain't one of them. This as a word of warning. But yeah, Fire Emblem is due in a few months and looks gorgeous, and while no advance wars you have quite some 3rd-party strategy games on the Switch, so it might be a worthy console for you.
