There's good value in this card as long as you have the annual fee waiver from the ongoing promotion and that you see the value on flying business class.
If you don't then the discussion is over, stick to Magnus because you can't exchange the business class voucher for several economy tickets which most people would rather find more useful and of more value.
Vistara has 1.2L spends for the waiver, I'd just get it and use it enough to get the annual fee waived and leave it on my drawer until it's time to cancel it.
Vistara Infinite monetary value ~53k INR for 1.2L spends:
- Business class voucher: 20k INR
- Upgrade vouchers x2: 20k INR
- 10k points milestone at 0.80p: 8k INR
- 3.6k CV points from 1.2L spends: 2.9k INR
- Vistara Gold (add your own value here) for a year which waives cancellation/change fees and some good perks.
- Golf 6 lessons/games per year (no value for most)
Magnus monetary value ~30k INR for 1.2L spends, about ~40k INR when optimizing spends:
- Milestone (32k points) 25k points once transferred 5:4 at 0.80p: 20k INR
- 10k INR Tatacliq voucher/flight.
Even if you optimize by using the GrabDeals and Gyftr for your usual purchases, in my case I get an extra value of ~11k INR per month on usual expenses which still can't match the Vistara Infinite, again just because of that 1.2L spend waiver and up to that initial spend, over that is better to switch to Magnus. On top of that CV Gold can be valuable, I'd find that value around 15k yearly in my use case but it will depend on how often you fly Vistara and use these perks, but I'll leave that out of the equation.
In example for my Gyftr/GrabDeals monthly purchases:
- ForestEssentials/Marks&Spencers GrabDeals spends of ~3.5k-4k nets you 10k ER: 6.4k INR
- Amazon Pay GV 10k INR (ER X3 so 1.8k ER): 1.1k INR
- Amazon Shopping GV 10K INR (ER X5 so 3k ER): 1.9k INR
- Swiggy GV 10k INR (ER X5 so 3k ER): 1.9k INR
Meet and Greet services which is of not much value domestically or mostly nominal value for most, the remaining benefits aren't very relevant to compare or any different.
So all in all, in that 1.2L spends you'll get better monetary value out of this Vistara Infinite promotion.
However most people here don't fly business and aren't willing to pay for it, it's more of a novelty experience. With the usual mindset around it's inefficient use of rewards as if they had points in lieu of the voucher they'd often book economy.
So most will find more value to have 40k CV points from a Magnus (50k ER when optmizing spends) which equals to about 8 one-way domestic flights in the most common routes between metros on Vistara or about 5 one way flights on Air India (via United Mileage Plus). You might be able to get better rates from other StarAlliance airlines partners rather than United but it's also troublesome to book and usually has steep surcharge fees.
After that initial 1.2L you can get more value (and even CV points) per month on a Magnus (even without the milestone benefit) than on the Vistara Infinite. They oughtta fix that as there's not much value in Vistara Infinite compared to Magnus without this ongoing offer.
If you travel often and use TravelEdge or Gyftr for MMT/Yatra vouchers, that's a no brainer: go for Magnus.
Do mind these theoretical situations and spends are based on genuine and common use of a Magnus with 1L+ spends.
