Two years, you got more than twice the life out of your blades.
Everyone, including Toyota, recommends replacing wiper blades every 6-12 months. For that reason alone I don't get the super fancy ones. Living in the PNW it makes sense for us to do as well because we get so much precipitation.
I only buy the OEM wipers at this point. Usually get 1-2 years out of them. Back with my 03, I'd be replacing them every 6 months and I tried so many different brands before settling back to the OEM wipers.
I like the Bosch Icon blades. I also use Rain-X on the windows and that helps the blades travel better. I replace them when they need it. They're a consumable maintenance item.
