The second link you supplied takes you to this page:
Get the set that I circled. Those happen to be the exact ones that I now own and use in conjunction with my cue cards. I thought that you were looking for one chord per card. The other link you provided shows cards with a LOT of very obscure chords, at least to anyone but a professional. The circled set has all the chords (and perhaps the only chords) that you'll need for a long time.
Actually, the set of 3 cards to the left of the ones I circled would work well too. Both have the same chord sheet plus one or two additional sheets. Which one to get depends on whether you want to focus on barre chords (circled set) or scales and triads (set to the left of circled).
