@CharliefromLI I've been waiting for the same sale at BJ's, so I bought some Royal Oak at Home Depot when it was on sale a couple weeks back, and I LOVED it. I'm only a few cooks into my new stash of (made in USA) Frontier, so I can't be entirely fair about comparing it. But I'd say they are very close in quality. The Frontier tends to have much larger chunks, while the few bags of RO I've tried are much more consistent. It's a pain to chop those chunks down to size, but I suppose that's still a lot better than buying lump with tiny pieces in the bags...
Also I must be getting old because those 35lb bags of Frontier are getting a bit heavy to tip into a chimney...
Bottom line, IMO it's too close to call. I'd go with whatever was cheaper, or easier to get.
