Many people adore the Gill Sans family. It has its own significant following amongst professionals in the know, and, due to its ubiquity there, it is called the Helvetica of England. This quintessential “British typeface” can seem straightforward and frank but still has an inherent warmth due to the humanist touches throughout. The choice of spurless forms (e.g., b, d, p, q) adds only more to the humanist feel.
But I am not a fan of Gill Sans. So much so, in fact, I have disabled it on my computer.
