In the grand scheme of things, the text link would be the preferred method.
But, you are getting the next best thing which is an image link. Just be sure they include a proper alt attribute for your Logo image. Adding the alt attribute with the image link provides an added benefit.
I'd also look at what is surrounding your image link. There are "outside influences" that come into play when we're talking about image links and their placement.
