Best in Split A/C category

Which suits best for my room?
For a room of 10*10 (approx 100 to 120 SFT size) or less -- 1 Ton will be sufficient
And for a room of size 110 to 180 SFT, 1.5 ton is required.
Another important point over here is; if you are looking for just bed-room use, go for 3-start. That would be enough. 5-star is recommended for ATM like stores where A/C has to be ON continually. 

Best Brands based on their quality in Split A/C products?
1st Quality (Premium): Mitsubishi, Hitachi, Daikin
2nd quality: Carrier, O-General, Voltas, BlueStar, Lloyd 
3rd grade: LG, Samsung, Whirlpool, Onida (These vendors will just assemble parts from different companies and put their brand label and marketing. So, not the best when it comes to quality A/C products from these companies)

*Again, this is not to promote or degrade any single brand. BTW, I dont have shares in any of those companies :-)

What was my decision finally?
After evaluating all the parameters like (i) Power Saving options, (ii) Best Service in Hyd especially, (iii) Top Quality in quick cooling, (iv) Maintenance, (v) Features being offered in each brand/model,...etc, we finally went for Hitachi 1.5 Ton - Kaze model. It has got all the features like Personalization/MyMode, Auto, Cool, Super Cool, Humidity, AreaCodeTechnology, Asynchronous & Parallel air flow, Silent mode, Quick Cooling...etc. And we're loving it.
