Here's a question: How would you compare 4 walks vs 1 HR? Which would you rather have in any given game (you're not allowed to know the situations)?
And on a side discussion, a somewhat pointless topic... a lead-off walk is no different then any other method of getting to 1B to lead-off an inning.

A lead-off runner has about 38% chance of scoring (regardless of how they got on). I'll take the way under on that for the Blue Jays this year.
