We use both, not on the same jobs. Painted for most new low-end construction and PVC on existing or high-end homes. The painted does tend to scratch much more easily but it can almost always be cleaned up again with a little WD-40. It also takes paint well and is often painted when used to wrap windows in the foundation. The only time the PVC has ever had the cracking on the hem issue is when it is very cold, as long as the metal is kept warm just before use this is not a problem. I use only smooth painted when make a 4x4 post a column(series of 3/4" z bends and wrap around post, staple in the over-lap seam, paint staples).
