I also prefer the blueberry on vocals. The Blueberry is one of the only mics I have ever owned that I don't go through love/hate phases with. It is always a strong contender, if not not my number one choice when it comes to vocals.
The TLM 103 is not a bad mic by any means, but it just does not seem to have the "Neumann magic" that really earned Neumann it's reputation. It always sounds nice, but often gets a little lost when mixing. I may end up rebuying one in the future, but it's not at the top of my list as far as LD condensors go.
In the TLM/Blueberry price range, you may want to also look at the Soundelux U195. It is also a solid contender in the $1000 price range.
