I am writing this from Maverick and agree with you, Exploder. This release may be a small step in features, but it is a huge leap in refinement. There has been a great deal of attention to the details, and the overall impression is slick and professional. Mint still has a big edge in newbie friendliness, but it's got some catching up to do in visual finish.
I do like the new Ubuntu font, with a big reservation. It looks great as the font for menus, titles, etc., but it falls short as a text font for readability. For this purpose, it is not as good as the default font used for this forum. As a test, I used your opening post in this thread, which contains long paragraphs. When Firefox displays it using the default font, there is ample white space between words and lines to make it easy to read very quickly. When I forced a change to Ubuntu, enough of this white space disappears, forcing the reader to slow down to absorb the words.
You can repeat the test in Firefox this way. Edit, Preferences, Content, select Ubuntu as the default font. Select Advanced (be sure Ubuntu is the Sans Serif choice, and that Sans Serif is chosen for Proportional). Compare with the option, "Allow pages to choose . . . " checked and unchecked.
