Their products are usable and uncluttered. I have reservations about the new unified look (too much padding in horizontal stripes one can't scroll, trying to displace browser chrome), but I've been very happy with the previous, “designed by engineers” Google aesthetic.
There are so many UX problems with the current crop of Google core products, it's hard for me to agree that "usable and uncluttered" can refer to anything but the Google of the past.
