I like Moore's much better. It is very similar to Dale's but has a lot less salt, so you can combine it with a rub. I like to put Moore's marinade (one TBS per side) on steak with a light coating of McCormick's Montreal Steak Seasoning. Tastes great!
I should add I grew up in Alabama, where both Dale's and Moore's are from, and they have been kept in my pantry for over 30 years, so I'm pretty familiar with em.
