I think my favorite cheats were one of the following
BoloPatch for Just Cause 2: Just the grappling hook editor alone should have been a feature. This was something that made the game tons more fun at a tradeoff for a little difficulty decrease (Unless you were using the other features of the trainer).
Ragdoll mode in Minority Report: MR was an okay game. But I discovered a glitch within a cheat that essentially made me cry with laughter every time I used it. When Ragdoll mode was active, a single button press would collapse Jon Anderton into a pile of limbs until he stopped moving, where he would get back up. Fun by itself. Then you combine this with a flaw in the game's combat system, where a ragdolling hit would negate gravity on the model for a split second if the target was in the air. Thus was born Ragdoll surfing. I would run, jump, and ragdoll, and careen through the air like a human cartwheel gone loose. Too much fun.
Half-Life 2 Demo Console shenanigans: I was fairly young when HL2 came out, and I had neither a great computer, nor a source of income. So I downloaded the demo. I love it. I played through it a ton of times. Then, one day I caught G4's Cheat!, with a segment on half-life 2. I immediately ran to their website, tried out some of their codes (Gravity, impulse 101, etc) and a whole new game started for me. With a little more research, I had found out how to spawn NPCs with a single keypress, light people on fire ("ent_fire !picker ignite" is still my favorite source command) and spawn massive armies while AI was disabled so they could fight it out when they came back.
Those three are the most memorable examples of "Cheating" in my mind, and they are so because they vastly improved the game I was playing. I still run back to HL2 (Now that I own The Orange box) and rebind everything for maximum shenanigans.
