Life

  1. Life at Delhi is the same like at Chennai, and it’s not that bad.
  2. Life of Delhi is the same like Chennai, and it’s not that bad.
  3. Life is the same like Chennai, and it’s not that bad.
  4. Life is the same, and it’s not that bad.
    Please correct all and comment.
    Can I replace ‘that bad’ with ‘so bad’? Will it be alright?
    Thanks.

IMHO, the phrase “the same like” is not correct in your sentences. As far as I know “the same as” is OK.

I would endorse what Foreigner says and add:
4. Life is the same, and it’s not that bad.
Life is the same, whether at (in) Delhi or Chennai, and it’s not that bad.
