Which platform is easiest to claim on?

None is easier in general. It depends on whether a route fits your facts.

Do I need three separate claims?

Yes. Each platform has its own namespace and its own process.

Which one has the tightest limits?

Snapchat, because of the length range and the yearly change limit.

Username claims on Instagram vs TikTok vs Snapchat

Short answer: the three platforms differ in rules and routes. Instagram has named reports and allows 30 characters. TikTok says it can rarely reassign a username and allows one change every 30 days. Snapchat allows 3 to 15 characters and one change every 12 months. Usernm covers all three.
