I would go with the Panworld. But I also have a Sicce 5.0 on my 60 gallon seahorse tank. Stuff is always slower than it says and if you have multiple outlets to create all of your flow from your return pump then it will be lots of little trickles IMO. (my Sicce is adjustable so I did turn it down a tad and am not running it on full 5.0.)

I bought spaflex and ended up hating it so the reef tank was hybdrid for awhile and now is mostly back to hard plumbing. With the seahorse tank I'm back to hard plumbing and no spaflex.
I don't know if you can get it locally but I love the Gorilla PVC glue more than the primer/cement combo.
