I have not seen a City Connect set yet that didn't make me want to hurl. The number fonts, in particular, have been wretched to the point of embarrassment. (Dodgers CC's excepted.) One of the (many) reasons I don't like the Twins current set is the number font.
MLB block numbers are fine for many reasons. Legibility being one of the most important. I can't wait for this "custom number fonts for everybody" era to be over...but sadly, it will probably outlive me. (Or, at least, what's left of my fandom.)
