In general, Kermit should be faster.

Xmodem and it's derivatives send a packet and wait for positive acknowledgement, while Kermit using a 'sliding window'. The sliding window allows Kermit to keep sending data before previous data has been acknowledged, making better use of the available bandwidth.
