I stuck in the same dilemma as u... But left out vu completely due to their awful after sales feedback I've been getting and as a product too not too sure according to most people here too have told me to stay away from vu.
As of now my contenders are lg 49 inch n maybe panssonic 49" or infocus 60 though it's a complete gamble to go fr this brand. Panasonic as well has bad after sales Ive noticed even in a place like gurgaon. So leaning towards the basic lg 49 inch and then 3 yrs down thr like look for a good 60-65 inch... And maybe oled at that time.
Regarding Philips 4k in case ur looking at, I already have one and u can go through the 55 inch uhd thread where in I've posted my feedback and ordeal I am going through.
Its a good Tv fr a good price consedring it's 4k n great after sales in gurgaon region. But, got it replaced due to excessive Backlight bleeding issues in the 49 inch model.. So that's a warning from my side. I've been told it's present in all Philips 4k n getting a refund now from them. U can see photos n my story on the thread.
Stay away from tcl too, non existent after sales and Backlight bleeding n clouding issues, though good PQ and quality of their 48 inch curved but iffy experience due to after sales n the panel issues.
