Personally, its all up to your tastes and the environment you grow it in. Some monster yielders are susceptible to mold and pests and others aren't. try something with solid hybrid vigor, if you want something cheap that can finish fast and produce quality yield, and alot of it, try something like Nirvana's PPP, you have to select from maybe 20-30 plants to get something consistently good, but they're a solid variety to start and similar in effect to sour diesel, in my opinion it is a cleaner buzz and more upbeat while sour d is, stupifying and physically soaring if you get the good shit it will have make your ears ring, the PPP I got back in 2010 was the same, smoke enough and you would have to lie down, focus and re adjust. stuff gave you the meanest munchies after an hour and the high would last a solid 3 hours like that then crash. The sativa leaning PPP they had produces really spirally flowers, all the way up the stems and not much trace of indica, they smelled and tasted like licorice/anisette liqour. PPP is cheap as hell too, 100 seeds after discount is like 200-220 so 30-40 seeds is under 100 bucks. As with all Dutch brands, you need to select from a large enough pool to get what you need, and they're all bred for indoor production(commercial).
Real sour D takes 11-12 weeks for flowering, PPP finishes around 9 weeks, some slightly earlier.
