Having trained in lash extensions with a few companies, I would firstly want to see the trainers work, not the companies cover photo's but their own work, I would also want to know what their training covered, also what support they provide afterwards. How many people are in a class, do you use a dummy head or a model to practice.
Sorry I haven't trained with any of the companies you have mentioned. But unless you have trained with more than one its hard to compare.
