Haha..Ignore it..Ye railfans site hai..everyone is somewhat biased towards their favourite trains..even I am..but the thing is that kuch teenagers jinko jyada exposure nahi hai other trains ka,wo apne favourite trains ke duniya mein hi khoye rehte hai..jaise jaise traveling exposure badhega,neutral hote jayenge (not 100%).. can't expect too much maturity from a 15 year old..so better ignore.
Regarding maintenance of SK,it's fine..at least whenever I have travelled (2A & 3A)..Barring few trips,I had no issues..but still,everyone have their own experiences..let's agree to disagree and move on.
