These are all good mics. I would suggest, if possible, you borrow or get one of each from a supplier and try thrm out.
Keep the one you like the best.
In my personal opinion I prefer the TB-1 for most vocals with the C3 next and the NTK last. I have used all 3 in recording situations and each has a unique character of its own.
Tough call.
Best of luck,
