CRI is import for sure but in real world testing just about nothing I'm nature likes to reflect light at 6k. Nature is yellow and brown and reflects like hell at 4300 but terrible at even 5000 much less higher. The white is pretty at 5000 and reflects white concrete pretty well but at the cost of depth perception. There's a world of difference between my 5000k of past and 4300 of current car.
