Which 1B will be the best

Who should I add?

Scoring categories:  R, RBI, AVG, OBP, SLG, NSB
NSB = net stolen bases, but for the purpose of this poll, you can ignore it.

Some of my thoughts

Jackson is hitting well and producing so far.
Honestly though, the best thing he has going for him is his home park and teammates.

Jacobs is hitting homers left and right, he is also in his age 27 season.
His AVG could be pretty poor and his OBP could be downright horrible.

Kotchman is really hitting well right now and is even hitting a few homers.
Will he keep the power up or has he just been lucky?

Votto probably has the highest upside.  He is just starting to heat up.
Is he still a year away?  Is Don Baker actually going to limit his PT via Hatteberg?

Please tell me your thoughts and don't limit yourself to discussing my above comments.  Any relevant information on any of the players will be greatly appreciated.

I think it is a toss up between Kotchman and Conor Jackson.  Both will hit for high average and have great plate discipline.  Don't get carried away by early season stats.  Both of these guys are better overall hitters than Jacobs and over the course of a season, I would take either Kotchman or Jackson over Jacobs.  If HR was a category, then Jacobs would be more of a consideration.

I'd pass on Votto because he isn't getting full-time at bats right now.  Dusty Baker even said he thinks Hatteberg is a better hitter right now and because of that, the two will continue to platoon.

Thank you for backing up my answer Conor Jackson!  4-5 with a single, two triples, and a HR last night.  Jackson has notoriously slow starter too!  This could be the year he puts a good first half of the season together with a good second half.

Jackson for President!
