They look exactly the same speed-wise to me:

 >>> t1 = Timer('randrange(100) in foo', 'from random import randrange; 
foo = set(xrange(1000))')
 >>> t2 = Timer('randrange(100) in foo', 'from random import randrange; 
foo = dict.fromkeys(xrange(1000))')
 >>> t1.timeit()
3.0573790073394775
 >>> t2.timeit()
3.064924955368042
 >>> t2.timeit()
3.0590860843658447
