Pros and cons of charcoal grills?

Disadvantages of charcoal grills:
Longer heating times. Charcoal grills take an average of 15-20 minutes to reach the proper cooking temperature (not including the time it takes to light the charcoal), whereas gas grills can be lit immediately and take about 10 minutes to reach cooking temperature. There are also several different ways to start a charcoal grill.
Fuel costs can add up. A 20-pound propane tank will provide about 25 days of cooking time, while a 20-pound bag of charcoal will only grill three times. The type of charcoal also changes the flavor of the food. A 20-pound bag of clean-burning hardwood/lump charcoal costs between $35 and $40.
Cleanup is a bit trickier. Gas grills require only a quick scrubbing with a brush, while charcoal grills must be scrubbed only after pouring off the ashes of use. Be sure to follow these grill cleaning tips, too.

Benefits of charcoal grills:
Typically, charcoal grills are hotter than gas grills. The temperature of the grill has to reach at least 600 degrees Fahrenheit to cook delicious meat. This is not a problem for a kettle grill filled with red-hot charcoal (speaking of which, did you know that you can turn a kettle grill into a pizza oven with a simple toolkit) because it can reach temperatures up to 700 degrees Fahrenheit. While there are also gas grills with higher temperatures, they are usually more expensive.
You get a delicious smoky flavor. Ever wondered how charcoal grills can deliver so much flavor? Turns out, high heat is the key. When the oils from your steak, chicken or veggies drip down onto the hot coals, they turn into flavor-filled steam and smoke that goes right into the meat, resulting in amazingly unique charcoal grill flavors.
Save more money. A basic charcoal grill costs about $25, and a mid-priced charcoal grill costs about $150. Of course, higher-end models will cost more, but in comparison, charcoal grills are much less expensive than gas grills, which typically cost between $130 and $300.
