The only times I really cheat in FTB is when a bug / annoying feature does something buggy / annoying, like spawning in a bucket when I accidentally right click my Liquid Force filled Tank with one, or giving myself "starter materials" so I don't have to go through the initial "punch trees, get wood, wood pick, get stone" grind again for the umpteenth time.
Plus, keepInventory is true and mobGriefing is false on my server, so it's really more of a "let's see what we can create now" instead of "let's kill this guy and steal his stuff" kind of deal - PvP's only on because there are glitches to get around PvP being off anyway.
(Also if turning UU-Matter into Gold Ore just to EE into other items counts as cheating, I cheat that way too )
