I use heel-toe in gt5p for fun and realism, but I think it's easier in real life because you can feel the car and it's much more evident if you did it properly or not.
<rant>Reality is also easier because gt5 has that stupid ridiculous unrealistic neutral penalty which is always messing up my shifting. I think it's supposed to keep people from flat shifting, but it's incredibly annoying imo. In a real car, I can feel when the clutch engages, and even if I do mis-shift, the car doesn't just go to neutral.

(sorry, just had a bad drive and needed an excuse to rant.)
