There have recently been a few new paints I have been using.
For your decks and wood surfaces a great product is Flood stain.  This warranty stain is sold by ICI and is a hybrid latex/oil product that has excellent adhesion, durability, and colour retention.  It also has an extended manufacturers warranty, the longest of any other stain on the market

My ” go to” product ICI Diamond has just released a new satin sheen that can withstand some moisture after application.  Also this product is a little thicker than the semi gloss alternative, and a bit less shiny so the coverage is far better.

Just a couple alternative products to consider in additon to the regular product mix I use
