There's basically no difference in the "security" of using the card physical contacts to power/communicate with the on-card chip vs using NFC for the same thing.
What is secure is not about the communications, it's about what information is exchanged, how the dynamic CVV is generated and used, how the PIN is validated in a Chip+PIN environment.
The PIN pad, where you enter the PIN is just as secure using the contacts or contactless. The PIN doesn't leave the PIN pad in the clear.
