Is CA articleship at big-4's worth it?

I recently joined a small firm as an article, my friends however joined big-4's, I see them working 15hr/day whereas I'm working around 8-9hrs, I get the hype of a brand name and all but does it actually help in the long run? I wanted to join big-4 but despite clearing in 1st attempt with regular college(university of delhi) , I didn't receive any calls from any big-4s.

Should I take a transfer if an opportunity comes up or wait for industrial? Views?
