It depends on the purpose. Introductory materials sometimes use a large enough note that they can write the letter name inside the note head. (Works better for black note heads.)
The redundancy helps associate the name and position.
I don't think I would prefer it in this case. The extra note name information is visually noisy and detracts from the shape of the line, which is mostly what experienced musicians see. The shape of the line, the absence of sharp and flat marks, and remembering what key you are playing in, covers most of your reading.
