I've only used PayPal Here, and it works just fine for me. I don't do much in the way of business and it goes in waves (months go by without a CC sale, and then I do a craft show and there are a dozen in a single day), so it's nice that there is no monthly fee. I also love that it doesn't require my phone to be a WiFi hotspot, just that it have internet access, so I don't have to pay extra on my wireless bill in order for it to work. The fees are more than reasonable, and I've never had a problem using it. My customers can use Visa/MC/Discover/Amex, or their PayPal accounts if they'd rather, so I've never had a problem accepting any kind of payment from anyone. It even has the capability of scanning personal checks, although as a rule I don't accept them from anyone I don't know personally. The money I receive goes into my PayPal account, and from there I can transfer it to my bank account if I wish. The one from PayPal was also free, and the app is free, which could very well be true of the others as well, but I thought I'd throw that out there in case it isn't.
My friend, on the other hand, couldn't make the one from PayPal work for her to save her life, so she ended up going with Square. She swears by it, but then she also does a great deal more volume on a regular basis than I do.
The only thing I don't like about any of them is they won't work if your phone is in a case because it doesn't allow them to plug in far enough. So when I'm at a craft show I have to uncase my phone, which I truly hate doing because I'm a klutz. But that's true regardless of which model you use.
