Either is a good choice. They both need to be taken care of in your climate. I have seen my share of stainless guns that looked great on the outside and were rusted and in terrible shape on the inside. Which ever one you get, part of the routine needs to be a good clean and light lube often. I'm sure you are already a where of this. Just throwing it out there. Some think stainless means no worries. They rust. usually from the inside out.
