Obviously the sales numbers will tell their own story, but I suspect most people aren't interested in the distillates, especially now you can get just a single full spectrum strain and no guff in the resin/rosin ones
I've really liked the TW (Train Wreck) by Somaí - even though it is a Hybrid, I've used it for nighttime and it has helped me relax and get a good night's sleep.
I also got SSC (Super Sour Candy) by Somaí, which is a Sativa, and it's been a good daytime vape, helps calm me down, but I can still go about my day.
