Since you are talking about something with a sanded texture to prevent slipping, I am going to toss out MY experience with the various Behr brand textured porch and deck paints and stains. My experience on two different decks on my house, one done in a Behr "stain" and the other in their outdoor porch/floor paint that has a sandy/gritty texture in it, is that *BOTH* of them peel due to foot traffic and sun exposure over time. I've found I am repainting the darned decks, railings and stairs at least every other year, over the past 7-8 years since I painted them.
Also, go with the lightest color you can. My wife wanted a dark brown. That turned the wood into a blazing furnace to your feet and the dogs feet once the hot summer sun hit it. We had to repaint that one with a light beige tint. I still feel the paint makes it hotter than if I had just put down some cheap Thompson water seal type stain over the wood. The other small deck and set of stairs and railings has a dark brown semi-translucent stain from Home Depot. It tends to stay "sticky" for a long long time. We used it inside the screened porch over there, and if I had to do it again, I would not go that direction - at least not for the deck boards and steps.
