I've done upper/lower/upper/lower before and I didn't really like it, I guess it would be convinient (butchered that spelling) if you were short on time.
It all depends on your training style really, I like high intensity and quite a bit of volume... I also love being in the gym, so I do a 5 on 1 off schedule hitting a bodypart every 6 days.
Personally I'd spend AT LEAST 5 days a week in the gym for weights even when cutting, it gives you more flexibility and allows you to give more attention to various bodyparts.
That being said, if i was forced (and i'd have to be) to pick a split out of the ones you posted, i'd choose the last one.
