I can see that it might take some getting used to, but I suspect the 
context managers are the better style: it clearly denotes the lifespan 
of the managed object, and provides for resource clean-up.  (I know, 
files are already automatically cleaned up -- at least in cpython; but 
not every managed object will be a file.)
