I have only participated in leagues that draft in person and auction style. I have no experience with any online leagues and was hoping to get some recommendations, input, etc.

I would like to find a deep NL-only league, auction or snake draft, that doesn't allow trading but has some type of daily or weekly faab/pick ups. Are there particular sites or hosts that are better run than others? Do most of the leagues have strong participation or do owners sign up, draft a team and then disappear? Open to paying for a league too. I appreciate the help!
