HDFC Credit Cards HDFC GVP Milestone Voucher to go for?

[provost]

I recently completed the milestone of 1.5L as part of HDFC Global Value Program. Details here: https://offers.smartbuy.hdfcbank.com/offer_details/gvp/24664/Z2epmWc=

Now, I have a choice between MMT, EasyMyTrip, Yatra and Cleartrip e-vouchers. If anyone has an experience in past with these e-vouchers, which one would you recommend? My primary criteria is multi use (all of them seem to be) and if other discounts can be stacked on top of these.

Makemytrip or Easemytrip. MMT has one of the largest variety/portfolios of options (i.e. hotel listings, flight options etc.), you can use coupons along with the voucher. Their flight prices can sometimes be higher than other websites so do check other OTAs. Their hotel rates are usually quite competitive.
EMT used to have quite reasonable or usually the lowest flight fares (before they went public). I've never personally used EMT with a voucher so can't comment on the usage of coupon code along with the voucher
