When I first started in this business I was a reseller.
That being said I can safely say that there is NO advantage in going with a reseller.

That doesn't mean that it's a bad idea to go with a reseller, but in reality, if you do your research you are always going to find superior hosting with a brick and mortar hosting service.
The best reseller out there is only as good as their host. If that host is outstanding then obviously it makes more sense to go to the source.
