As a former CPGer myself -- a few thoughts.
P&G is always the best... although most go with the expectation of getting 'picked off' and leaving within 4-7 years.
Unilever is great b/c if you are cool w/ NYC-area, it's a great place to start and there are countless 'next job' options that won't require you to move.
Many ppl who go to General Mills think "It's going to be too cold" but wind up loving it and staying there for a LONG time.
Honestly, can't miss on any of the three -- be sure to consider full picture and not just company (location, friends, etc.)
Congrats!
