most potent/fastest maturing strain...

hey guys. I havent posted in a while but i have been sitting bak watching the posts. A question just popped into my head, I was wandering, in your guys's opinion, out of the many seedbanks what is....
1. the most potent plant....
2. the fastest maturing plant
3. The biggest producer in terms of final yield.

Of course, i know everyone will have different opinions on this probably, but just let me know thru ur experience which type of plant falls into these three catagories. I will then use that info to pick out the top species of plants to grow - i want a plant for very potent bud, one more a good yeild and one to mature early so i can harvest early. I heard big bud is a good producer, but im not sure - which is why I have come to my great experienced friends here at this forum. I really appreciate the help, thanks alot
PS - this is for outdoor plants
