I recommend you stick to Daredevil. Penny Dreadful S2 also had some pretty good episodes and works to a satisfying conclusion so I did not regret watching it, but your life won't be much richer for watching it either.
GoT is pretty good, but I am getting a bit tired of imagining for how long they will be able to stretch out the inevitable thing it seems to work towards. I am enjoying it, but not excited by it.
I am also following Orphan Black, which after a brief moment of hesitation about why the new season even exists has totally justified itself and has me hooked. It is just really enjoyable to watch.
Finally, every time I am down with anything like a flu and my mental faculties are reduced, I am capable of enjoying Arrow, though this time despite being ill I am still occasionally offended by the ham-fisted acting and dwelling on superficial emotions.
My wife also lives Sherlock - I haven't tried it much (assuming you mean the Lucy Liu version)
