What's your favorite dwarf automatic?

In my state the law counts stems and roots as equal to cured buds when considering weight. For less than 200 grams, there's no court or arrest, only a fine, but the more weight the heavier the charges. A man could face a felony charge for a large plant even if it had no buds on it.

It's to my best interest to raise only dwarf plants but I have no experience with them at all. What's more, the seed banks tend to praise each strain as though it were the worlds best. Feedback here would help me narrow down the search for a tiny seed.

So what's your favorite dwarf automatic?

 

No personal experience growing any of these, but "green-o-matic" from greenhouse seeds is said to be the fastest autoflowering strain in the world, and greenhouse is one of the most reputable seed companies.
