The AT2020, you're gonna place that on a stand and probably have a pop filter. The singer will engage with it differently. It's not gonna be as versatile for performing, but it will probably sound better on a recording.

There's always exceptions - some voices just work well with a certain dynamic mic f.ex. But for recording, I use condensers. I'd consider ribbon mics too, but they seem too fragile and so I haven't dared

While I think you'd be just fine with the Shures in terms of gain, there's no question AT2020 will work well in this regard.
