Every time I've thought about moving away from Namecheap to something else I've remembered those once in a blue moon times I've actually needed to reach out to support for mission critical type of events. The support I've received has been absolutely stellar. Above and beyond what I would have expected to be their scope of service. I don't know any other providers I hold as highly in support, especially anything coming from a tech company.
My main gripe is that I wish they would include free SSL and they give their UI some love but that's minor as I only access it on certain occasions.
