Should I switch from Sitechecker?

Only if you were paying for monitoring you do not use. If you need alerts when a template breaks across 10,000 URLs, Sitechecker is the right class of tool.

Can I scan without an account?

Yes on SEO King, with a daily cap. Sitechecker’s deeper crawl sits behind a trial or plan.
