Not sure I should fill the poll : as someone with a higher minimum font size --so not using the zooming tool-- and a mouse user, the only menus I found usable (because I could see the text clearly and fully, understand quickly how they worked and easily select stuff) were strict XHTML, HTML5, Dropper Dropdown Menu, and Simply Accessible. Customized OAA Menubar and Suckerfish and Son of Suckerfish could have probably worked for me with some different styling.
