Do I need a side burner?

Reviewers are split. Verified-purchase customers at Home Depot and Lowe's frequently call side burners useful for sauces, sides or boiling corn without going inside, but several r/grilling threads point out the side burner is often the first feature owners stop using. If counter-style outdoor cooking matters to you, models like the Spirit E-435 include one; if not, you can save money skipping it.
