I have a love for many shows: The Walking Dead, Always Sunny in Philadelphia, Big Bang Theory, and so on.
MLP:FiM for me has greatly influenced my life since I started to watch it so is it my favorite show? No. I have many favorites, and it feels unfair to me to pick just one. I mean, I used to watch the old school Transformers as a kid. I loved that show so much and as I grew, my tastes changed.
Don't get me wrong, I adore FiM greatly. The characters, the storylines, the development. All of it encompasses one great show that I can really get behind as a fan.
So again, ask me if it's my favorite show. I can give you many reasons why it is a favorite of mine, and even compare it to ones that are a little lower on my favorites list. But again, I feel it is unfair to classify it among several other great shows in my opinion, just to deem which is superior.
