Funny...I was using an Anode but someone told me it wasn't a great putting putter. More for upshots and whatnot. I was putting pretty decent with the Anode except there was one glaring problem that he inadvertently hit on.
Anodes = $15
Magnet = $8
While I can afford an Anode, I knew I really needed to have 3 or 4 of the same putters in identical weight for practice. So, I bought some Magnets. I checked some out at the shop, they felt better than the Challenger so I rolled with a few soft magnets and regular magnets. Come to find out, my putting percentage on rounds increased...and surprisingly I liked the regular magnet as opposed to the soft magnet.
BUT! In no way do they fly the same. If you want to do a short anhyzer putt with a little movement they are quite different. I'd go with the magnet for putting and keep the Anode as once you progress in your game it will find a spot in your bag.
Side note...I liked the regular magnet so I switched to a stiffer putter. I use KC Pro Aviars now.
