Which is better for gaming, the C4 or the C6?

The C6. Both do 120Hz and four HDMI 2.1, but the C6 adds VRR up to 165Hz for PC and a 0.1ms response time. The C4 is G-Sync certified at 120Hz, which is plenty for PS5 and Xbox Series X.

Is the C6 worth the extra $155 over the C4?

Yes if you game on a PC or want the newer processor and webOS 26. If you mostly stream movies and shows, the C4's OLED picture is close and you keep the savings.

Which has better sound without a soundbar?

The C6. It has a 2.2-channel system with 4 speakers. The C4 uses a 2-channel setup. Both support Dolby Atmos, but a soundbar or AV receiver helps either one.

Do both support Dolby Vision and FILMMAKER MODE?

Yes. Both have Dolby Vision, Dolby Atmos and FILMMAKER MODE, so HDR movies look similar in tone and motion handling.
