RailFans - हमको देख देख दुनिया जले, हमको ज़माने से क्या

Hi guys , I am new to this forum as a member but have been following this site for some time .
Here is the dilemma .
I want to travel from NZM to MAS and am torn between the duronto, rajdhani and TN express .
My priorities are
1)...
more...

good food ,
2) cleanliness and
3) lesser time of travel
in order.
Which would you advise me to take . Though , I admire the fast trains , my friend has told me that MAS duronto had horrible food . Any suggestions .
Are there places to get food externally when travelling by duronto ? ( I know there are only 5 min tech halts )
Is the duronto punctual ?
Lastly , sorry for bothering you all with a long post . I am new around here
Thanks,
Akshay
