Which movie is better Cannibal Ferox or ZOMBI (or ZOMBI 2 it has multiple titles)?

My boyfriend is a horror movie buff, he has cannibal holocaust, and I know he wants both cannibal ferox, AND Zombi,(by luccio fulci) BUT I am getting only one of them for him for Valentines day, so which one do YOU think he would be more stoked on? they're both hard to find but I found on amazon, zombi is the 25th anniversary edition, oh and we've seen zombi, but we've never seen cannibal ferox. HELP! which should I get??
