Some of my favorites would be:
Ufotable's Unlimited Blade Works - Epic quality Ufotable animation paired up with Nasu's writing (except the mollusks, of course) is great. Dolphins again though.
Fate/Zero - Urobutcher's writing strikes again- this time in glorious Ufotable animation. No dolphins.
Aoki Hagane no Arpeggio - The anime-original end + CG animation weren't the best incentives out there, but the upcoming movies show some great potential. At least they did the original end better than some shows... (looking at you, AgK.) This choice might have some manga reading-bias added in. Heh.
Danshi Koukousei no Nichijou/ NichiBros - I have to admit, I simply laughed a lot in this show. Good comedy, sitcom-style moments, it's a shame the manga had to end.
Gintama - Comedy that'll make you laugh out loud even in the middle of the night and serious arcs that make you want to beg for more. Never ceases to amaze me.
