When you transitioned your LO out of the crib, did you move them to a toddler bed first, or straight in a bigger bed?

We are looking to transition LO2 in the next few months. Her 2nd birthday is coming up and we thought we would ask for stuff for her big girl bed. My parents are good about chipping in for stuff like that, which helps. But I wasn't sure if we should plan to just take her crib rail off first, and see how that goes, and then transition to a twin once we buy it or if it doesn't really make a difference either way? What did you do, and why?
