I've no experience with Mephisto but I can't see myself buying from them in the near future despite their proven quality genetics. The reason is the whole 'Monday madness' sales technique. Getting their customers to jump through hoops rubs me the wrong way. This is obviously an 'it's me not them' thing but i don't have any enthusiasm for that kind of environment.
I can browse many other seed providers in a relaxed manner and choose from quality genetics 6 days a week. The other sellers like Fast Buds, Sweetseeds, Seedman et al seem, to me, to be more appreciative of their customers. That being said, I'm new (or returning after 25 years hiatus) to the whole game and this is really just a personal opinion on what suits me, and not to whether Mephisto genetics are over hyped.
As to the hype, I think the quality difference to the other premium seed sellers is slight, yes good genetics are essential but looking at the experienced growers on this site who have their environments and techniques locked down, you could almost throw them a pumpkin seed and they'd produce two pounds of dry primo bud from it in two weeks.
I am obviously a newbie and my opinion is not worth the digital space it takes up but as a newbie i feel compelled to share my ill informed wisdom.
