Importing Version Specific Modules

Which method makes the most sense for importing a module in python
that is version specific? My use case is that I'm writing code that
will be deployed into a python 2.3 environment and in a few months be
upgraded to python 2.5. This:

if sys.version_info[:2] >= (2, 5):
    from string import Template
    from our.compat.string import Template

or this

    from string import Template
except ImportError:
    from our.compat.string import Template

I know that either case is equally correct and works correctly but
which one is preferable?
