In general, if game have separate settings for RT, enable reflections. It’s effective.
Huge update is path tracing.

Witcher 3 set to even RT minimum seems to have big difference but still no need to use it.

Hitman WoA seems mostly better without RT https://youtu.be/DBNH0NyN8K8?t=1041
Also huge performance drop like 65% https://youtu.be/qTeKzJsoL3k?t=806

Cyberpunk 2077, RT low pointless, very limited impact,
RT ultra - big visual impact.
Overdrive awesome, huge impact, looks like other game.

Resolution of reflections can introduce noise which can be distracting .
If dev uses denoising, it can produce boiling image, constantly moving shadow on textures. Boiling artifacts

Blur

New games are kinda blurry mess because of problems with motion
