The top b-schools globally are just a filtering mechanism. The value add by b-schools per se is not very high. Any IIM grad would have 95%+ similar output on his job even if they never did an MBA. Apart from hard skills like accounting, finance - there is not much to learn at there.
The real value is scoring 99.5%ile in CAT (hence sharpening your basic reasoning skills) and being around folks who are pushing themselves all the time (high quality assignment submissions, case competition, sports etc). You cannot replicate this in a 3rd place
I have been bearish on the value prop of alternative b-schools. Tech skills are still very tangible - building an application teaches you more about tech than making a ppy teaches you about business
