I like them but I like using chunks as well in combination.
Depending on the planned burn time and type of cooker, you need a lot of chips, and the JD chips aren't cheap.
At the end of the day though, if you did two side by side cooks, one with JD Oak and the other with regular oak chips, the finished product would probably have minimal differences or be hard to ID which was which.
Don't get caught up in the marketing part of the "JD"
