I like Optimize my core starters because of my desire to wait on kickers defense and backups. The function includes a starting QB and TE as well as backups, but with core starters, I basically am telling the program to focus on RBs/WRs and at least one backup at each of those spots before recommending other positions. Also, I find this option is more inclined to show me a RB when I already have 2 WRs instead of showing me the best WR on the board, which I like.

I trust my evaluation of late round guys, so the optimize core starters one works best for me. I usually have specific guys that I'm targeting late anyway and know generally when I can get them.
