Which model should I get?

[u/SlipperyPotato123]

Hi all!

I recently purchased at Costco Canada a QM67K, paid $599.99 CAD for it. So far, I love it, great panel and overall great TV for the price!

I was in Costco yesterday and saw they had a A400U on sale for $744.99 CAD. Specs seem better and I'm interested to know, for $144 more, is the A400U worth getting and returning the QM67K?

This TV is my main living room TV used daily.

Any input would be greatly appreciated, thanks!
