I would go for the 2nd one.
Number 1 isn't stunning by any stretch of the imagination, in fact it is down right tacky.
Number 1 may well have the extra bedroom but the bedrooms look tiny.
Number 2 is detached which makes a huge difference, in a nicer area, yes it is very dated in decoration but surely no one would actually leave number 1 decorated the way it is and you could split the master bedroom in to two good sized rooms if you really wanted the extra room.
Also in the long term with number 2 you will be able to increase the value of the house with ease.
