I don't think B is drab or soulless it's jumble empty and need filling!
The important fundamentals are done and the same in both - bathroom, kitchen etc, so ultimately it's going to come down to what you get for your money, the location and how you feel about each.
Sorry that's not helpful, but I can't choose between them on paper, if that's the only choice.
If I was able to be really picky, I wouldn't choose either because one is a terrace with nor parking outside and one doesn't 'look' as lovely. But then again, I live in a house which doesn't have max curb appeal but after a lot of badgering by the EA, I did come and look round and I love it. It just isn't a period property, but that's why we could, afford it. That's the importance of seeing them in real life vs just online!
