Sump experience

[PilotMaximus]

EShopps R300 vs EShopps RS300 vs Deep Blue Promaxx RS300. Wondering if anyone has had experience with these threes sumps. Either firsthand or maybe someone you trust have given a few pros and cons. Obviously they are on the cheaper side. One thing I noticed in the store was the Deep Blue used Rectangle filter socks. Any thoughts are welcome.

Thanks
