too many multimode blue diodes, any comparisons?

[Maltes]

Leaving the obvious 445/450nm vs 462/465nm difference aside, there still seem to be way more blue multimode diodes to choose from than what is the case with multimode red diodes or greens.

There's NDB7875 which is very affordable.
There's NUBM07E which seems it would be the brightest
But there is also NUBM08, NUBM06, NUBM05, NUBM44.
I'd like to think the low number NUBM's are just lower power versions of a diode with the same beam profile, but I at least know the NUBM08 is worse with divergence compared to NUBM07 or NDB7875 and I know NUBM44 has poor divergence. But I haven't found more info beyond that. My budget is also preventing me from getting them all and just comparing myself.
Ha anyone had a chance to compare all these NUBMs?

Bump. DTR also now lists all of these blue diodes in his shop.

My opinion is the differences in wavelength and power are what counts here. You get what you get in terms of divergence. First chose the color and then compare the options by power. I like 462nm. But I also only use one diode. After cyl lens they match my green almost exactly.
