Normal settings are arp=enabled and add-arp not set. Anything else is set for some particular reason, some "cooking recipes" advise to set arp=reply-only and add-arp=yes to force clients to use DHCP server assigned IP addresses instead of anything else (e.g. manually set IP addresses) ... or arp=proxy-arp to fix some "problem" with communication between clients in different L2 segments (and the reasons to do it are most of times the wrong ones).
