The best word to use depends on the specific situation. For example, if you're giving a recommendation for a job candidate, you might use "endorsement" or "referral." If you're suggesting a restaurant to a friend, you might use "tip" or "best bet."
It's also important to consider the tone of your writing. If you're writing formally, you'll want to use more formal language. If you're writing informally, you can use more casual language.
