Every host is a reseller of some sort, and to some degree, but I know what you mean. I would say one advantage of going with a reseller would be support. IF the upstream provider has a solid network and everything is fine at that end, then a reseller (usually with less clients) would be able to give better individual support. Although, that really is a generalization as every company is different. Besides, IF it is a good reseller for a good upstream host, then the reseller would (should) have a better relationship with the host than a individual possibly could. Another might be that the reseller might offer more services such as web design, seo, submissions, etc. Of course this is only one way of looking at things. There are of course plenty of cons with going with a reseller so it will be interesting to see what others have to say.
