I think given the right situation any sub offered would be satisfactory to someone. On SMD there are a lot of factors that come into play. How many watts can it handle, What's the xmax, does the sub like a sealed or ported enclosure, is it an SQ sub or more of an SPL thing, (what freebies do we get!) but one thing that I do like is that I have seen a lot of comments regarding customer service. That is a really big issue because no one wants to invest time and money on a sub just to have it blow, become damaged, etc. and have to deal with a crappy company that wants everything short of a DNA sample to receive satisfactory service. I am choosing to run Sundown equipment not only off of the reputation of the subs, but the reputation of the company and what kind of service they provide their customers and not just the customer who is competing for them, or the one who is mortgaging their future to have a setup but also the poor college student who has a family to support but also wants to have some fun when it comes to his favorite pasttime. (That would be me) Don't just be sold on a name truly research as many aspects as possible and if you are truly satisfied, it won't matter to you whether we like the company or not. (sorry for the long message)
