How exactly is the ability to come back to life (a single time) handy if you want to peep?

The Doa Doa is the only logical choice, since it not only allows SAFE peeping, but enables you to actually get to the peeping spot in the first place.

The Suke Suke no Mi wont help you if the locker room is closed, so it isn't all that helpful.

The Yomi Yomi no Mi allows you to pass through objects, but it doesn't make you invisible. The opposite is the case, you will scare the ladies (which will cover their private parts ASAP and run for their life's ).

And you forgot the Horo Horo no Mi, which basically allows for simultaneous peeping using the hollows all over the city. However it suffers from being visible and creepy as well.

Thus, it is the Doa Doa no Mi.
