BT, I've done lots of studio work over the years, a while back it was work your bits out and don't make mistakes.
I'm lucky that I'm never short of ideas but I found the first take with me always had the best feel so then I'd work on the accuracy and re record.
Later on, working with the same producers time and again you realize where the edit points are so you can drop in to repair which is less stressful when the clock is ticking. When I'm recording in my home studio even as I'm creating parts I always have half a brain on where these edit points are - it means you can free flow ideas without having to constantly restart yet still keep a lot of those first bursts of creativity.
As Per says though, whatever works for you. Sometimes changing approach on a different track gives you a bit more freedom.
