1. AK-47 Serious Seeds - 2009: Ran her for almost 3 years. She yielded very well even under my severely under-powered lights, basically I could do no wrong with her which was good, because after 12 years of learning, I did a lot wrong and she still loved me regardless. I'm considering getting their current pheno and seeing what I could do with her after a decade of practice.
2. Dairy Queen: TGA - Subcool, 2014. Nice smooth smoke, yielded well, produced really sweet oil from the trim, worked well in my system back then. Friends came back a lot to smoke her with me. She was an all around crowd pleasing flower.
3. Think Fast by Dutch Passion 2020. My current girl is probably one of my favorites. Really sweet flavor right out of the drying closet, flavor profiles develop and change dramatically after about 2 months of curing and she can be a one hit-quit after full cure. Plays very nicely with the Nectar nutrients and absolutely loves being blasted with the full power of the HLG330 R-spec in flower. Yielded an even pound in 1/2 m/s closet.
Runner Up Critical Sensi-Star - Delicious Seeds. She was a great plant, yielded well and tasted great but my personal flavor leans towards sativas, and for an indica dom, she was one of the best I ran.
Most difficult Tangi: DNA genetics. 2015 I don't know if it was the pheno or just my little 450w HPS back then, but she crawled up and over my light after growing into it real fast after flipping to flower. Went from short and bushy to leggy, almost a vine within a week of flipping to flower. Her buds were sometimes inches apart and really tiny. I honestly think she just needed more light than I had in my closet. The upside was she gave me the best tasting BHO I've ever made and the yield of BHO was quit impressive even if the flower yield wasn't.
