Vegas Hotels Strato vs. Excalibur vs. Luxor

[loose passive]

I am looking at some air/hotel packages to come out to vegas. I have a few hotel options and I am wondering which is best. I would like something nice and fairly close to the action on the strip.

Here are the hotels and price differences. This is for two nights.
Stratosphere = Cheapest
Excalibur = +$90
Luxor = +$140

which would you chose?
