Handstand, headstand, forearm stand

Hi! Not super new to yoga, but new to what I consider more difficult poses. I really want to work on my handstand this year and also want to work on my headstand / forearm stand. I am curious whether I should start working on a headstand or forearm stand first? I know people are different but is one considered easier? Any advice / poses to work on leading up to those would be much appreciated!
