Which is better for console gaming?

The onn. Its 144 Hz panel adds FreeSync, ALLM and VRR, which the Philips 60 Hz set does not list. On a PS5 or Xbox you get smoother motion and less tearing on the onn.

Which has the better picture?

Both are QLED 4K with HDR, so they are close. The onn is larger at 55 inches, which matters more for immersion. The Philips states a wide viewing angle, so it holds up better when people sit off to the side.

Is the Philips worth stepping down in size for?

Only if 55 inches is too big for your room or you watch from wide angles. Otherwise the onn gives you more screen and far more gaming capability for the same class of TV.

Which is more reliable?

Hard to say. The Philips has 701 ratings averaging 3.5, which is a broad but average record. The onn has only 36 ratings at 3.7, too few to judge long-term reliability.

Do both run Google TV?

Yes, both are Google smart TVs with Google Assistant. The onn also lists Amazon Alexa and Siri support, and the Philips adds Chromecast built in for casting from a phone.

Which is easier to wall mount?

Both are flat with three HDMI ports and VESA mounting. The Philips is slimmer at 2.7 in deep versus 3.5 in on the onn, so it sits closer to the wall.

onn 55" QLED 4K Gaming Google TV vs Philips Class QLED 4K Google TV

The onn is the better pick for gaming and for anyone who wants a big 55-inch screen with 144 Hz, FreeSync, ALLM and VRR. The Philips is a smaller 43-inch 60 Hz set with a wide viewing angle and Chromecast built in, better suited to a bedroom or a bright room with side seating. Build and owner feedback are mixed on both: the onn's 3.7 rating from 36 ratings is thin, and the Philips' 3.5 from 701 ratings reflects a long track record of average satisfaction. Neither is a premium panel, so buy on the feature that matters to you.

Choose the onn if you play console or PC games and want a 55-inch 144 Hz QLED with FreeSync, ALLM and VRR.
Choose the Philips if you want a smaller 43-inch QLED with a wide viewing angle and built-in Chromecast for a bedroom or side-seating room.
