I used White Glove--about 15 years ago--and I was not pleased with the attitude of their employees or the service rendered by them.
That being said, the crews on moving trucks change very rapidly in many cases, and the quality of the service that you receive is highly dependent on who is working for the company on that particular day. Also--for all I know, White Glove might be owned by different folks nowadays, so my somewhat unhappy experience should not be interpreted as an assurance that you would be disappointed with their service.
