Different Flex welcome offers, your opinion?

Hello guys, me and my partner recently reverted back to using Monzo as our main spending account, and we both upgraded to Monzo Perks as well.

I've just noticed a banner at the top of the app highlighting some Monzo Flex promo, available until the 17th April.

Thing is, the promo seem to be different for the two of us, and even after searching online I can't see anyone talking about these promos.

Thing is, being us new to Flex, we don't know very well how they differ from the standard Flex offering (to be clear: I'm not new to credit cards, however I find the whole documentation about Flex very confusing lol).

Image 1: my phone, with a promo giving purchases > £100 (made in the first 90 days) no interest for 12 monthly payments.

Image 2: his phone, with a promo giving 2% cashback at major UK supermarkets for th first 60 days.

Has anyone else got one of them? How are you finding it?

Is my offer (12months interest free for purchases above £100 in the first 90 days) something noteworthy?

Or do they make these sorts of offers every few months even for people who already have a Flex card/account?

Thank you!
