Nopes 12424 is better than it, u can see the time taken by both rajdhani they are same and even howrah rajdhani and patna rajdhani also same, 12424 se jb mai gya tha to ye 16 min early thi kanpur me aur mgs me 12 minutes vo b 1st week of January us time fog b hota h but us din ye har roz ki tarah 2,3 hours delay nhi thi even it reach bju 20 minutes early, bs pnbe me 8 min delay thi
Bro i have never travelled in 12424 dibrugarh rajdhani. So i can't say about it. I felt BBS rajdhani is best as far my experience is concerned. Above blog i have alreay told which rajdhanis i have travelled and out of those BBS rajdhani via adra is my favourite.
