Steroidology isn't the proper forum for asking about which UG Labs produce the best gear. Many of the UG Labs that will be endorsed have gone private so you won't be able to obtain their gear no matter how much you would like to try it. Also, as dann69 has pointed out, these private UG Labs do not want their names mentioned on any board for obvious reasons.
If you're truly interested in trying a UG Lab's product, ask the question on a website that allows open source posting. At least then if you get a consensus on any one particular UG Lab, you'll have the opportunity to purchase their products and try them out for yourself.
