I've used every single font on that list. By far, my favorites would have to be Tahoma, Georgia, Lucida Sans Unicode, Calibri, and Arial. My least favorites are Comic Sans MS, Times New Roman, Century Gothic and Impact. Impact is not cool, bro. I can only see Courier New in an old letter from the 1880's.
It's not because everyone hates it, but it's because I find my posts silly looking with Comic Sans MS. I still cringe whenever I view my first posts because it was... Comic Sans MS and purple. Nowadays, my default font is Tahoma. It's definitely my most used one. I hate opening Microsoft Words and seeing Times New Roman as my default font. I always change it to Calibri instead. Georgia was really fun to use and refreshing. I remember using Arial for a while, but I chose to stick with Tahoma instead.
