Wave maker or return pump

[thisguy1]

So I’m having a hard time deciding on which way to increase the flow inside my tank. I’m debating on getting the hygger wavemaker 1600 model or the mightyjet 538 with a spinstream attachment. Just would like some other input on which is better. My tank is the IM 15 gallon
