I redid my deck 5 years ago with this:
TimberTech Terrain Collection 47/50 in. x 5-9/25 in. x 12 ft. Rustic Elm Grooved Capped Composite Decking Board-TCGV5412RE - The Home Depot
It is T&G so all fasteners are hidden. Easy to cut and install. Looks great still with zero maintenance. I would do this again. The only downside I notice is that in the summer it gets quite hot. Not comfortable for bare feet in 100F outside temps so I always wear shoes or flops.
