Only you can answer such... Some people only like new stuffs, others don't. IMO, same price and a 5 years warranty from say Harvey Norman? I'd take the 65"..

Such fear is normal. Which is why I pointed out the seller. If it's some random seller that I'm unsure of their extended warranty or heck, if they'll still be in business in 5 years?.. Then I'd skip. HM? Good.

Take some video samples and test the display for defects, can claim on the spot before taking delivery (store dependent).

Spec wise is more or less identical. But whichever your budget tell you to.

Just take note that if you don't need the TV in a hurry, the MU series will be starting their price slash within this 4-5 months

In fact the price slash already started, but the amount will only grow bigger as time pass.

might need it this month though. usually the biggest sales is the end of the year? what about merdeka sale? haha

Curve meh?
I saw few stores... MU6300 are non curve le... even few reviews too. But of coz review are got curve version.

When I making comparison between, MU6000 vs MU6100 and MU6300. MU6300 colors are richer.

Sample non curve MU6300:

Don't check the models from other countries, we don't get a lot of those TV models available at other countries unfortunately. We can only check the review as the reference, however the specs might be different. Below is the MU6300 for Malaysia:
