In terms of Visual Quality, nothing beats the movies and OVAs.
Garden of feet (and other miyazaki movies), ufotable's KnK movies, and all the GiTS are beautiful spectacles for the eyes.
In terms of a great story, it generally takes a lot more than what japan's finest can offer to take a very well written story, and then adapt it from its base medium to anime to be a new and unique product that caters to more than just the people who read the manga/book and then want to watch it read to them and voiced by actors line for line.
In that sense of Quality work, I find Gintama, the meta-tier 4koma/LN adaptations (GJ-bu, ichiban seitokai, etc.), and then a very, very select few gems of anime original works (milky holmes S1, Lain, FMP:Fu) that fall into that category.
in terms of enjoyment, nothing beats the fantasy hot blooded wish fullment shows, notably Ichiban Daimaou, chrome shelled regios, legend of the lengary heroes, and sengoku basara.
Just turn off your brain, smile because you know what's being subtly parodied and referenced, and enjoy the escapism at its finest.
