As everybody has said, it really is all about personal preference. However, there are Nichia emitters with 90+ CRI and 5000k plus CCT. The Nichia 219B V1 comes in a SW57 tint that's rated at 5700 kelvin, but is more like around 5400 kelvin.
Here is an example of a cheap light that comes with such an LED:

I was so intrigued with this light that I had to pick one up myself (because for the longest time I was after a light with a high CRI nichia with higher CCT, as I found the tint of the SW45 at 4500kelvin too tannish.)
I think the light is cheap enough that you can get one and experiment to see if the tint is right for you or not. As far as the light looking too cool, I say that in general, it really isn't that cool looking. The light has a high amount of deep red (R9) rendition-- even higher than the 4500k Nichias, so it has a lot of inner warmth to it. In fact, its combination of pure whiteness, combined with its high amount of deep red rendering, makes my 4500k Nichia look a tad green in comparison. The difference is especially noticeable on skin tones, where the 4500k 219B looks nowhere near as natural as the 5400k 219B V1.
As far as LEDs that are available in 5k + CCT with high CRI, Cree makes their XHP series LEDs available in high CRI with high CCTs, Osram makes such LEDs as well, and so does Yuji. Here is a video showing off the color rendering prowess of a sunlight balanced LED (5600k) with 96 CRI from Yuji.

I'm not aware of any flashlight that comes standard with them. Zebralight has plans on an SC600F with one such high CRI (93-95) rated at 5000k, but it isn't on the market yet.
As you can see, the color accuracy of the Yuji is stupidly good, however the LED itself is very big and a power hungry monster. It can't be used in a normal sized flashlight; but it gives a taste of just how warm and accurate high CRI lights in the 5500k+ kelvin range can be when there's a healthy amount of deep red saturation.
