I found this bit of info. Might be food for thought. I always go for the indoor cannabis. Maybe I need to try more of the outdoor strains this fall during harvest time in the Pacific NW.
Outdoor cannabis is better because the sun’s natural light spectrum produces more cannabinoids and terpenes, increasing the plant’s flavor and potency—the two qualities every cannabis aficionado values. A Washington State–certified lab compared 2,700 samples and found that sun-grown cannabis was at least 1 percent higher in THC than indoor plants; likewise, terpene response is best under the sun. And when light-deprivation techniques are used, outdoor cannabis delivers the highest quality, regardless of whether it’s sativa or indica.
Edit
The indoor cannabis always looks better to the eye than the outdoor IMO. The indoor always looks fuller and tighter buds. Maybe looks doesn't always matter.
