I have a Zillion, Curado 101D and Revo STX's in my arsenal. I have the Zillion on my 7' H Dobyns 704c rod and I use it for throwing frogs, jigs, small swimbaits and c-rigs.
My opinion? Depends on what you're planning to throw. It's a very solid, smooth reel that I like a lot. Casts well, feels great, easy to adjust...But it clearly excels in some areas and not in others. I'd recommend this reel for throwing lures that are ~3/8 oz and above. For weightless or lightly weighted plastics, or ~1/4 oz hardbaits, I'd recommend something else.
