The WinterHold house is the best, imo. More merchants too and close to Stormcloak.
Winterhold? Don't think there is a house for purchase there. U mean Windhelm or Whiterun?
It is on Xbox as well, I had all my cool stuff on the shelves, I cam back into the house to find it all laying on the floor across the room. Also my save is cursed by the weapon rack glitch that doesn't allow to to put weapons in the racks.
For me this glitch is just for the whiterun house. Ive bought all the houses and only the one in whiterun has a problems with the racks and wall plaques

Love the houses in Windhelm and Solitude. Huge with lots of display cases, mannequins for amor, weapon racks and wall plaques
