Switching beds

My daughter is currently in a crib but can climb out so it’s time to move her into a new bed. I can’t seem to figure out if I want to switch to a toddler or just a go to a twin bed with rails. She is super tall for 1.5 years old. She about 34inches tall if not taller. She basically has a few inches left in her crib before touching on both sides.: what have you done? What was the easier change?
