Keep it to CSM unless you want to exclusively boot from UEFI.

UEFI is faster to boot.

Not really, that highly depends on the amount of bloat your board has the load and the speed of the board. And once the OS launches what will make the difference is AHCI vs Legacy.

CSM means UEFI but also compatible with BIOS. Not all devices and software supports UEFI. You are choosing between having both or just having one.

Faster boot and better power management.2 This is especially true for Windows – depending on various factors, UEFI with Fast Boot can be even twice as fast as legacy boot. With Linux the difference will be smaller, but still present. This is because BIOS-booted OS needs to re-initialize some hardware that might have been already initialized, the initial OS code needs to be loaded in very slow legacy modes, etc.

I forget to mention the fastboot.

A fun talk between uefi and legacy.

Like I said, highly depends on the amount of bloat it needs to load.

If I were to Coreboot my motherboard it would post a lot faster then that same board with it's stock firmware and UEFI.
