Pigtail seems to be the most legit. A large business, a great
instagram following with tons of pics, vids etc. Goes and gets clones direct, just like today she posted several stories going to Cookies to buy the Jealousy F1 clone drop and pics of it as well so you know it is 100% legit. Serious connections from what I can tell and very well taken care of. My PKB clone from her is the best of the bunch (day 3F). I also love that they are bigger clones not just in rockwool but in small bags of coco and rooted further and far more established. Success rate is much much higher.
Lab Hollow I have 2 still in early veg so I can't say much, but packaging is extremely legit as is company side from what I can tell. They also came in soil containers and further along. I will update as we go on their RS11 and White Tahoe Cookies.
I also have 2 Prestige Clones Blue Cookies early goings so far also. His customer service was great for me, I had ordered on the weekend and it hadn't shipped end of Tues so I reached out and he forgot the order and didn't ship until Thursday so sent me 3 when I ordered 1. Can't beat that.
I just think you have to take your time and do some research and you'll find there are a few sellers that are very legit.
