What is the difference between the Jebao wave makers??

[Tangina20]

I have a 40 breeder and I’m currently only using the return pump as my only source of flow and have been looking in to getting a wave maker. I think I only need/want 1 for now. I see Jabao pp, ow, sow, and rw series they all look the same to me and cost about the same?? Which one is the newest and what would you recommend for my tank with mostly lps(doesn’t have to be a jabao)?

The different series are models. OW is the newest, PP is the predecessor I believe. Nothing wrong with either of those two.
