I've been using Biotrue Multi Purpose Solution for years, and it's consistently kept my contacts comfortable all day long. It's preservative-free and pH balanced like tears, so my eyes always feel fresh and never irritated. The case it comes with is nice too, but more importantly, this solution genuinely makes wearing lenses a pleasant experience without any stinging or dry spots.
