Yo. Mr. Arcfan here.
Dana's got you covered. BUT "better" tint is quite subjective. Some people like the SB2 better than the SB1. I may actually be one of them, but I'm not sure. I tend to like whichever one I'm using at the moment. With the standard V3.1 out, there are many advantages of the standard over the LE now.
They are now both HA III, they have the same brightness of white LED, and they work the same.
The differences? The LE is the only way to get the "natural" color. But if you want black, the standard now features Chemkote throughout (like Surefire) and has a roll crimp at the base of the head for better grounding. The very last few LE's had their heads Chemkoted, but I have yet to hear of one that had Chemkote in the body as well.
Really what makes them valuable is that they're Limited (and say so, right on them!). The Standard AAA is a fantastic light, and is better in many ways. If you actually use the light, don't feel like you're missing too much. I say this stuff until I'm blue in the face, but few actually believe me.
When the LE first came out, the standard had a less-bright LED, and the standard was not HA III. The LE was a huge stand-out at the time. Now it has been surpassed in everyway except case color and LED tint.
Good enough?
