Best Stain for a Deck Restoration Contractor.

I am a contractor and have used Sherwin Willams products in the past. Wondering about what you would recommend? I am in Iowa so hot summers and hot winters. Contractors in my area use Deck Defender, and Ready seal stains. I have read the reviews of restore a deck products but am hesitant to use water-based products. I like Sherwin because of the ease of pickup but would like to find a higher quality product. Thanks
