Check out the spectral plots comparisons for your favorite bulbs, it's wild how close some of the bulbs are to each other, and then there are the weird ones like the xm20k... Crazy spike @ 450.

Awesome!

I was thinking about what to replace my 10k Ushios with... maybe go with more Ushios..... what's the deal with the spike on hte XM 20k's??

Looks like from the performance data and spectrum, that 10k XM's would put out the most output in a general pleasing "white" spectrum, like the Ushios do.
