Blank Keycaps vs Labeled Keys

Should you buy a keyboard with blank keycaps?

Blank keycaps forces you learn touch-type, because you can't hunt and peck, you have to put hands in touch-type position and use muscle memory to type.

Problem with blank keycaps is that it's hard to use the keyboard casually, because there's no distinguishing mark on the keys. You must put your hands in touch-type position.

Once you know how to touch-type, keyboard with no mark on keys is annoying.

If you do any design of layout, or change keybinding, key label helps a lot. What exactly is printed on them doesn't matter, but something, that can help distinguish one cell from a array of cells. (for example, design key layout or keybinding layout in emacs, that supports QWERTY, Dvorak, Colemak, etc.)
