Xiaomi Phone 2 review: high-end specs in a surprisingly affordable package
That review is from ENGADGET. You'll find several other reviews for the above as well.
And S3? Its slower than the MI2, and as for your infinite love for all-things-apple/samsung, the S3 has that very well-known sudden death issue.
=========
Now to OP, if you aren't a brand freak (and technically ignorant), the MI2 is your best choice in this budget. Ofc if you 'stretch' your budget, you can get the Xperia Z for about 65,000. It has the same processor as the MI2 just so you know
Mi2 is faster than both One X and S3. If you're OK with the plastic body (S3 has the same), then go for it.
