Yup, both of those will work. Square bases are super easy, with round beveled bases you have to skew and curve the font to make it readable.
Maybe take a look at Letrasets too, I've used those in the past to good effect.

Also you could just write on the bases with a fine tipped permanent pen.
Or practice your freehand, it's the only way you'll get better!
