I really really like ATCM, JTTCOTT was god awful and for a long time NIS was my favourite episode of Series 7 but I do think its superior to the others.

1: Nightmare in Silver
2: A Town Called Mercy
3: Journey to the Centre of the TARDIS

I'm okay about 'Journey...', but don't like 'Nightmare...' and 'A Town...'.

I love all of them but my order of preference has got to be:
1. Nightmare in Silver
2. A Town Called Mercy
3. Journey :)

i like this episode because we finally see the cybermen actually scary, and i just loved the way Matt portrayed Mr. Clever its kinda like in a town called Mercy we see the Doctor getting angry and that its just an amazing sight to see and its progress on the Doctors character development. i love the other episodes too, but i liked this one the most out of the three

I think "A Town..." is an amazing and underrated episode

Loved this episode. I liked the Cyber-Planner that Matt played and the chemistry of Clara and the Doctor.

Couldn't decide between A town called mercy and nightmare in silver, journey to the centre of the tardis was okay, but not as good as these two.
