I'm about the furthest thing from a professional and have used maybe 3 mics, so I'll say it's teh best mic ever!
(typical inexperienced review)
In all seriousness, I'm really not a professional and I have only used a handful of mics and this one just a handful of times (mostly because I don't have time and haven't even messed with tracks I did back in March). The noise floor really is shockingly low, the mic really hates super close up vocals and will react violently to wind/puffs (my solution was a blast pad), the proximity effect super up close isn't that spectacular from what I could tell at the time. Otherwise, normal conditions it sounds fairly neutral. Maybe would be a good reference point, or good for quiet quiet mic'ing applications due to its self noise.
As far as the tone, I really couldn't tell you. It reproduces sound pretty well to my ears, there's some acoustic clips floating around if you search around that make it sound NICE, and it's on the clipalator as well, so that'd probably do better for you to judge its tone than any sort of adjective assembly I would pull out of my ass.
