If you have 10 full days I would do both.  The pro’s of the samples is it really challenges you to think and I have never taken Level I but I am fairly confident that is the hardest problems you will see.  The con’s are it is times 120 min for 60 questions set up to give you real time answers after each question.  Thus I think Schweser mocks are better aligned with real deal because it’s 120 q morning session and 120 q afternoon.  
At least do one.  It is only take 2 hours out of the 10 days you have left.  It will force your brain to think even harder/deeper which is a good thing.
