DY – I would understand the gemorah that the talmid chacham is presumed to be an oved Hashem, just like it is presumed that the talmid chacham is not an apikores. No one would recommend marrying Acher, even though he was a talmid chacham by any definition.
But sure, if you can be certain that you have an oved Hashem, a talmid chacham is a major plus. The problem is finding a real one, which is not so easy. Finally, a guy who insists he wants 10 years kollel and the support to back it up may not be the best place to find one.
