Personal preference.

I rarely pocket carry. Probably 99.9% of the time I carry it's IWB at around 3:30-4:00. That's where most of my training and experience has been. It's what I'm habituated to. I've been hesitant to try alternate positions because I'm concerned that I will revert to how I've been trained and go for a gun on my right hip if I'm carrying elsewhere on my body and I need to respond. Which is why when I do pocket carry, or when I carry in my fanny pack when out jogging, I always spend a few minutes doing a few dry-fire drawing repetitions before heading out.

However, I will say that 2 hours is nothing. I don't like OWB because it always felt like my gun was pulling away from my body. However, I carried that way for over a week before I came to my conclusions.
