My favorite is a specific phenotype of bagseed I've been growing for years. I grew out about hundreds of seeds and dealt with tons of hermies, stretchy bastards, weak stemmed plants, and practically trichome-less plants before I came out with a few plants worth keeping. out of those select few, one stands out at the all around best.
Around here its called the SpruceZeus.
8-9 week strain that smells of fuel and fruitjuice. Vigorous growth.
The high is very balanced, with aspects of indica and sativa. Definitely some skunk in there. Good for pain relief, I prefer this to my much stronger White Rhino, because I can smoke it during the day without hard burnout, but it still helps with back pain.
I don't know if it really counts, as this isn't a strain availible at any seedbanks, However, word has it, some cuts of it are getting around. Keep your eyes open, might be at a dispensary near you soon.
