Bumpers or rails?

Lo

We’re about to move our 2 1/2 year old to a big girl bed. We have an extra Queen so we’re actually just moving her straight to that. She’s pretty active at night, but RARELY has to pee in the night.

Do you all have recommendations on those small foam bumpers (to keep her from rolling out) or the railing (to keep her totally contained until we come get her)? Not sure which to choose or which brands are best! TIA!
