I use a mix of both commercial rubs and home made. I have not found a commercial rub that touches the rib rub I use. Although I really like Fast Eddy rub on my grilled food. And Famous Dave's Chickn' Wing rub on my chicken wings. Then there's the Blazin' Blends Zesty Seasoned Salt that I get from the Dollar Tree that I love on grilled veggies and steaks.
