Book my show remains my first choice untill and unless they become ticketing partner to mass events. Its amazing how irctc has still better load performance than Bms. Firstly, they enable the ticketing 30 mins late and on the top of that, and probably use a reverse queue, to end up last ones to enter the queue on the top of the queue. The coldplay frenzy will somehow affect its footfall for uocoming mass events. I dont recommend trusting BMS for mass events.
