55 LPA in India v/s 3.6L AED in Dubai - Confused.

In a bit of a dilemma.

I joined a well-known / well -funded startup in a mid level role 3 days back.

A Dubai based startup that I had previously interviewed with a few months back, got back to me with a 30k AED / month offer yesterday.

Questions -

1. Is 30K AED a good salary for Dubai, considering what I make in India?
2. Would it reflect badly if I leave the current company in the first week, considering I made them wait for 2 months of my joining (I don't see my role as super critical for them).

From a job role POV, the dubai role feels more fulfilling. The India role offers a better employer brand.

What are your thoughts on what I should do?
