You really don't get it do you "handyman"? If you are anything close to what your name suggests you might be and that is a 'handy' 'man', the question asked by the op is something like me asking you, "handyman", "what's the best tool"?
It all depends. In this case, I have no idea where the op is located and therefore by definition almost, there is no right answer to his question. Even if we retain for the sake of argument, that he is looking for a grass seed 'for shade', I can give you that some bluegrasses fare better than bermuda grass but that supposes he has the choice of either one in the zone he lives in. Up here in the NorthEast, we don't have bermuda grasses, so no point going on about bermuda if he can't even buy it. So he's not looking for everyone'e experience...I mean who cares what success people have with seeds they have in Alaska if you live in Florida.
So everything, or most everything has to do with the other facets of lawns, soil type, location, seed type etc and even more has to do with good watering, fertilizing and aeration plans.
Lets have the couch potato tell us at least that much then maybe we'll help him out. It's just to easy to ask "What's the best...." thinking that there's one answer that everyone else has found - but that the poster can't be ****** to help us help him...
