DOS is a controversial halts given for one and not for other. Besides no stations in DTO route apart form GHD and DTO have a good quality station. WHile BKSC, KQR, and Gaya are A category.
Honestly neither deserved to get HE1 and AE1, for proof just check the current availability post chart preparation. both have same CC
I do it occasionally and found more than 50 in 1A and 80 in 2A empty for both. (Virtually going empty except for peak seasons)
That...
more... no. is surely less for 12439.
