If you're looking for a cozy and romantic ambiance, then a wood-burning fireplace is the way to go. There's nothing like the crackling sound of burning wood and the smell of smoke wafting through the air. Plus, you can roast marshmallows or make s'mores over an open flame! However, if you're more concerned with efficiency and convenience, then a gas fireplace is probably a better option. Gas fireplaces are much easier to start and maintain than wood-burning ones, and they don't produce as much smoke.
