In my opinion, ClearType text looks fuzzy and I like my text crisp and sharp. I have found that just turning ClearType off does not always really keep it turned off. On Windows 7 there is a ClearType Text Tuner dialog where you keep selecting which box of text looks best. Even though clearing the checkbox immediately seems to turn off ClearType, it does not stay off. You have to go through all the dialog boxes and select that last Finish button. You may need to close and reopen some applications or even log out and back in again.
