Corruption is generally easier for new characters to handle, especially considering Eater of Worlds vs. Brain of Cthulhu, but Crimson generally offers easier caverns to traverse without fall protection. Cursed Flames are easier to get than Ichor, Ichor is generally more useful. Personally, I consider it a tossup based on personal preference, and in my case, I have no such preference. I like having one of each in two (or more) different worlds so I can switch between them and use both sides together.
