The 4 bed, agree that the split living spaces is not appealing. Also the garden seems small and not very inviting, and the rooms look small and cramped. I can't see how 4 bedrooms worth of people could comfortably use the living space. The kitchen and bathrooms are serviceable but aren't very nice.
It also looks like the same people have been trying to sell it since 2022, so I'd be concerned there's something wrong with it that's coming up on searches etc. Or that they're flaky and keep pulling out.
The 3 bed looks better, has photographed much more nicely, is bigger and importantly just looks like there is space. The garden is larger, the living room is connected to the garden, and there is the conservatory. The bathrooms and kitchens aren't special, but they look much better.
