Finding the perfect OWB takes some time and $ investment. What one person may reccomend may not work well with you. I personally prefer a high riding vertical canted, close to my body OWB worn around 3:30-4:00. So far of all the OWB's I have tried and there have been many, I found Mitch Rosen's UPL to be perfect for me although there is no sweat shield to protect your body from the slide. I agree that IWB is not comfortable although there are a select few that I really like (Bulman's PDL)
Here is a crappy pic of my G23 in the Express (cheaper) Rosen UPL
