well i have have in my tank right now 4-mj1200 with mods ,2Koralia #4 and 2-Koralia#3 and a tunze 6100
Im in the process of getting more mj with mods and another 6100. To replace the koralia's
And i would have to say that i would rather have the MJ or the tunze over the koralia.
with the way they are on the mag you can only position them so far to one side.
And for the price of a mj 1200 with mod and a magnet they are almost the same price as a #4 if not cheaper.
Never used the vortech so cant give any input on them.
