Creating Custom Cards with CardGenR: What's Your Experience?

Hey everyone! I’m contemplating using CardGenR to create some custom cards for a couple of upcoming birthdays. I want to make them unique and personal. The last time I tried designing a card, I got so bogged down with options that I ended up frustrated and just bought something off the shelf. Has anyone had a good experience with fake credit card generator? Any tips or features I should definitely check out?
