from what i've seen and grown, Chernobyl and Qrazy train were the best. Not alot of Trainwreck to cross my path, but none were cured well enough or gave me the high my homegrown gave so i give you those 2 since they were really good imo. other than that, i say Pineapple Express, it's also great smoke but i haven't grown it.
the chernobyl takes 9-11 weeks to reach perfection, lemon-limey and needs about 1 month veg before flowering to give excellent yields, the Qrazy train can go 9 weeks and be perfect(less sativa than chernobyl) but smells like Querkle and citrus or whine, kinda grape-like but gives a stronger body high and eases away stress and pain on a much more satisfactory level compared to chernobyl which will leave you high in the clouds for 2-3 hours.
G13 labs makes the "Pineapple Express" while TGA subcool seeds makes the "Chernobyl" and "Qrazy train"
