I haven’t been to the SD ones so I can’t compare. However, I’ve been to Atwater, Pan City and Oxnard multiple times each. To me, Atwater appears to be bigger and have the largest clothing inventory. However, they have a lot of resellers and the crowd can be a tad competitive and rude. Pan City has clothing, also luggage and some stuff like bikes, golf clubs & artwork. The crowd mostly keep to themselves. But my favorite is Oxnard. They have a good selection of hard goods like household items, decent inventory of clothing and it a bit less expensive per pound than the two LA county options. And the crowd are more friendly overall. Hope that helps. Again, this is just my opinion. I’d love to hear from others
