Depends what you’re doing with them.
REPLACE INTOis technically faster since it doesn’t have to do a read before updating (but that is mostly irrelevant), but I’ve felt thatINSERT INTO ... ON DUPLICATE KEY UPDATEis generally more clear as to what you want to do.Here is a short discussion in a blog.
