Which is better for gaming, the U6 or the QD5?

The U6. It has a native 144Hz panel, VRR up to 240Hz and Game Booster 240. The QD5 is 60Hz with no VRR.

Is the U6 worth about $420 more than the QD5?

For a main TV, yes. Mini-LED local dimming, Dolby Vision and 144Hz are real upgrades over the QD5's basic 60Hz panel. For a bedroom or spare room, the QD5 is enough.

Which is better in a bright room?

The U6. It has an anti-glare, anti-reflection screen and Mini-LED brightness. The QD5 has no anti-glare spec listed.

Which has the better smart TV system?

It depends on preference. The U6 runs Google TV with Alexa support; the QD5 runs Roku TV, which many find simpler.

The U6 is 75 inches and about 73 inches wide. The QD5 is 55 inches and about 31.5 inches wide, so check your wall or stand space.

Neither maker publishes a lifespan figure. Both are LED-backlit LCD TVs; the U6's Mini-LED backlight has many more dimming zones, which is more complex but not a known reliability problem.
