I can't really provide any feedback on the quick lime. I've never used any of those products. Let me say that any lime, quick or not, will leach through sandy soil faster than other types of soil. Don't get too caught up in that. Any product you use is going to have to be reapplied every year or two.

You said "spread by hand". Does that mean slinging it out with a hand scoop of some kind? Again, I've never used the quick lime stuff, but the pelletized lime may be your best bet for trying to get even coverage by slinging it out. My thoughts are that the pellets will scatter better and more evenly.
