Difference between Samsung 55NU7372 and 49NU7302 ?

[voiha]

Hello,

I'm searching for a new TV, I stumbled upon good deal of Samsung 49NU7302 for about 525USD, I started researching about it but I haven't found much of a information about it except it's at the highest quality of the LED line-up from Samsung

So I understand that in 49NU7302 - 49 represents the size, N represents that's made in 2018, U that's LED and the rest is it's serial number something, if it's higher it's better, so here my question appeared

What is the difference between 7302 and 7372 ? Are these even up to date TV's ? Is there any better options around the same price ? That would be around 800-1000$

Thanks in advance !
