No one can say which it's best for you.
Everyone has his/her own opinions on the matter, but as per today grub4dos and Syslinux have roughly the same features.
I would say grub4dos, because I am more familiar with it, another member might say Syslinux, noone can say which one is better, and definitely NOT which one is better
for you.
