I Want to be sure about the root method & roms for Redmi Note 3

Hi,
With too many Redmi 3 sub-models, it hard for me to getting "knowing the ropes".

I bought the Redmi Note 3 Pro 3GB 32GB Qualcomm Snapdragon 650 Hexa Core.

I totally confused with:
- What is the Rooting method that works for this sub-model? (after sending request to Xiaomi to unlock the BL)
- I want a clean rom without Chinese bloatware - running smoothly without lags.

Please help me straighten out with this confusing area (for me).

Thanks you very much!
