I had a chance to try out the Bottle. If you already have a Blueberry and like the sound, then you will like the Bottle.
Personally, I did not choose any of the Blue mics. The ones I tried seemed to be harsh and noisy. They have their own sound and I would think that they wouldn't work well with female vocals. In my opinion, if you had one of the Creed type male singers, then this would probably be a good mic to use.
I can't compare to a C1 since I really have never had any experience with a C1.
