Dualshock 4 better for PS4 games on PS5?

I'm new to console buying and looking to play some PS4 exclusives on the PS5 but need some advice.

Is there a downside to using the Dualsense controller to play PS4 games on the PS5? The other way to ask it is does anyone know of a benefit of using a Dualshock 4 controller (vs. a Dualsense) to play PS4 games on the PS5? Are there features/functions that a Dualshock 4 has that the Dualsense doesn't have which PS4 games are designed to use?

Thanks

As far as I understand, all the features of the DS4 are present in the DualSense.

I'd opt for the DualSense just because it doesn't have the obnoxious blue light on it.

Dualsense all the way.

Appreciate it, less money I need to spend.
