(As always, I apologise as always if I posted this in the wrong forum but I don't have specific font sample to work with here.)
I am always bashing Comic Sans, but I would really like to find and suggest a solid alternative to it. My bank (Lloyd's TSB) use their own variant of VAG Rounded for almost all of their body text which is friendly and easy-to-read. Two prerequisites for the perfect font family/typeface to recommend.
A key issue with standard VAG Rounded is it suffers from homoglyph with a only a slightly larger stem on the "i" and "j" glyphs to differentiate between them. Which was rectified in the Lloyd's TSB version. As you can see from their website.
