Yes, there is. NFC enabled terminals may be the norm at major chain stores but they do not have widespread adoption in smaller retail outlets.
The merchant pays for those terminals and they are not inexpensive. Sometimes $1000 or more. That tradeoff (making it slightly easier for you to pay) just isn't worth it to most merchants right now. As EMV adoption grows and merchants have to update their terminals to support that as well, NFC will grow.
Also, it may seem as if ApplePay is more secure for the banks as it prevents issues with data breaches but to date, it has not prevented any, will continue to only lessen the impact and is absolutely wrought with card fraud as there isn't any validation that you own the card you are loading into ApplePay. Once it's loaded it isn't checked by the merchant (if the merchant even pays attention these days) and is implicitly trusted by the network.
