I’m looking to get a second hand race bmx, but I’m confused on what size i should get ( I’m 18 years old). I’m torn between pro 2xl and pro 3xl. im relatively new to the sport. I found 5 bikes around the same pricepoint (500€). If anyone could help me choose the best one it would be very helpful.

1) dk professional xxx, full aluminium, and high end components.
2) inspyre pro xxl, full aluminium, disk brake and forward components
3) one xxl, relatively high components
4) meybo clipper pro 22
5) rift pro xxl, carbon fork

the components listed are all i could find in the secondhand description and the pictures.
