Which TV is currently the best for the following data?

I would like to have a television for Christmas that has the following properties.

-40-50 inches

-4k resolution

Price 400 euro-450 euro

Samsung is good there, but Black Friday is already over.

The problem is that what now fits the price can be more expensive again in 2 weeks, but they are quite good for the price
