For me I like propane for the ease of cleanup and time spent cooking. I've never tried the charcoal/wood grills and I'm sure they're great but there are times during the week when I just don't have the time to spend watching the grill. For a weekend of leisure with plenty of time on my hands, I'm sure the charcoal/wood would be a great fit plus I don't have the space for 2 grills..Once again, thank you to everyone for all the opinions and info.
I feel like I'm leaning towards a medium size 3-burner propane grill of some sort with a basic Weber charcoal to work on learning that style if I can carve out space for both.
Just as an example, after making this post yesterday I realized that I didn't feel like having the drive in burgers that kid #1 requested (he got to pick dinner yesterday). So I grabbed a couple of chicken breasts, marinated for a bit, and then took them across the street to my old grill. Would I have made the last minute decision and spent the time/money to fire up a charcoal grill for two chicken breasts? I'm not sure that I would have.
On the other hand, all the folks who love charcoal aren't wrong. It's been too long since I've had some of that classic flavor...
