Most likely than not, they have legal basis for what they are asking for. Check with your lawyers and if they agree, you should just accept and move on. The distraction (and cost) of having to fight a legal battle to have a comparison page on your website is just not worth it for most startups.

We are a tiny company building an open-source alternative to an existing SaaS app and we have received two such letters in the last 6 months. First time I just replied in an email, second time I had the lawyers respond to create a legal trail. I don't think we were at fault in both the cases but it is still not worth it.

We checked VERY thoroughly. They don't have legal basis. Federal law specifically prohibit clauses that prevent open reviews. It is dubbed the 'yelp law'

I would double check that legal advice (assuming you actually consulted a competent attorney who specializes in this law). See my analysis elsewhere in this discussion.

This is not reasonable advice. 95% of lawyer's letters that we receive are without legal merit and do not lead to any legal action if ignored. You can generally tell which ones have merit. If you're not certain, sure you can ask a lawyer - but even asking a lawyer costs money, so don't bother for letters that are obviously attempts at intimidation.
