I almost always use a 50/50 mix of Kingsfords Comp briqs and what ever lump I have on hand. I've found that combination works for my long cooks very well.
For hot and fast cooks I like using just lump but I've not found a favorite brand yet.
Many posts here state that if you monitor the temps as they rise and start shutting down the air intake before your target temp any charcoal will hold the temp you want.
Example is when I want 225º at 190º I shut down the air intake to almost 10% and check again 15 minutes later, if the temp is still at 190º then I know I need to open one air intake a little bit more.
On my UDS if I want to cook at 350º I know that at 300º I'll shut down the air intake all the way down and when the temp rises near 350º I'll open the intakes a little bit and the temp seems to stay steady but I do monitor every half hour and adjust from there.
