Maxpect Gyres are slightly better than the IceCap but the IceCap are more favorable price. Both work really well with the WE.
I will say this I am unhappy with the magnets on the newer style Icecaps gyres because they are not as strong as Maxspect gyres and sometimes they wont stay straight so I prefer the Maxspect pumps now. IceCaps work perfectly fine though. I have never used the Maxpect jump line but they seem to have that same single magnet as my newer Icecaps but I can not say how strong they are since I have not used them.
I also own the Octo Pulse pumps which are great but I much prefer the flow of the Gyre style because they create a longer sheet of water and a more gentle flow vs prop pumps conical flow. Since the flow is wider there is also less dead spots and more coverage. That said the Gyre style pump are quite long. So for me where I cant fit my gyres I use Octo pulse pumps. The Octo pulse pumps are very easy to clean and produce some good flow for their size.
Like I said I love my gyres and prefer the flow vs any other pump on the market but the Octo Pulse are great too.
