I only use the buckets for bottling. Leakers were not my problem, but I always do 6 gallon batches and constantly found myself concerned with whether or not the bucket was going to foam over. I now use a 10 gallon Brute for my primary fermentations and couldn't be happier. The handles on the sides make it easy to lift. It is also easy to clean with no concern for the cleanliness of a spigot.
