Legrand 6" square LED in "Daylight" (6500k) or "Cool daylight/white" (4000k)Price is about RM 22 - 25 depending on the quantity you buy, and the relationship you have with the shop people. I prefer to buy from an electrical shop, as I try to support local businesses. The construction of the lights are good (in my opinion as a person with 2 pieces of paper in the relevant industry) and they come with a 2 year warranty. I don't really like the very yellow "warm white" (2700k - 3000k
Colour
Temperature), and I explain this to all my customers. Turns out most of them also agree with this once they know the difference.

From L to R : 6500k, 2700k, 4000k Colour Temperature light samples
I don't prefer Philips (I find the quality not that great actually), and don't mind Osram. But Osram does 2700k CT for warm colour, and I prefer a single brand across all the fittings. If you buy at a shop, you can also get a better
quantity discount.
I prefer square, because I think it looks better. Aligning the lights and making sure they are straight have stopped being a problem ever since I started using laser tools many, many years ago.
Some may say you should buy cheap, and replace when they die. Even though I make money from installing electrical items, I sincerely think you should buy quality, install once and then forget about it. After all, the price difference is about RM 10 from a cheap fitting. Maybe you can change the fitting yourself, and that is a great cost saving, but then can you be sure the fitting will be exactly the same, or even the CT? Sure, you can buy the "quality" non-branded, but how sure are you on the quality? Which forumer is going to tell you "I tested nnnnnn brand over 3 years, they were good, you can buy them here"? Just try to find the same Sh.pee or Laz.da shop after 3 years.
Let me give you an anecdote - You can buy a quality downlight from Wong Lighting, (if you are in PJ/KL) that they have gone to China and contract manufactured under their own brand name "Eluminuz". It's good quality, but the price is comparable to a branded downlight. In 3 years you'll have to go back to Wong lighting should you need a replacement, but if you bought Legrand/Osram/Philips, you'll be able to get a replacement in any electrical shop.
One final consideration. For my own place, I use downlights, but only when I need a lot of light in the area. Places like the kitchen, bathrooms, corridors etc. Living areas do have downlights, but the usually used illumination is from smart bulbs, where the brightness and the CT can be controlled using an app or Alexa/Google Home. These are installed in stand or table lamps. For bedrooms especially, I do not want lights from the ceiling shining directly into my eyes when I'm in bed. Plus the convenience of not having to get out of bed to turn OFF the lights when I'm ready to zzzzzz...
Sorry, not sorry for the long post. My good deed for the day posting as much information as I can, and the reasoning behind it, for you to read.
Edit : added a few sentences
