1G1R packs are easy to come by, maybe take a peek over at archive.org

I wouldn’t worry about what comes preloaded on the device, and instead focus on things like hardware/software quality, UI/UX, form factor, and compatibility with the games you’re interested in.

I’ve got an Analogue Pocket because I wanted to play a mix of physical and digital content and it’s great, but it really only plays up to GBA or so. No PS or more modern games, so there’s that potential downside.
