I have a Kuzma Stogi and I have used Benz cartridges on it for as long as I have had it. I now have a Benz M2 (M0.9) wood body on it and it mates well. The arm is used with a Sota Nova Series V TT with the Cosmos armboard.
As for comparisons, if I'm correct the Kuzma is in the $1500 range. It compares well in that price range to the lower level Graham and SMEs (which are also highly recommended for SOTA TTs), and if you're on a budget it will be less expensive than the higher end arms from those vendors, without sacrificing a lot of quality in the process.
I don't know what TT you are using, but in addition to the Kuzma you may want to look at the Hadcock arms that are referred to as the "poor mans" Shroeders. I have my sights set on a Shroeder Model 2 at $2400 as an eventual successor to the Kuzma.
The key is to make sure your TT, tomearm, cartridge and phono stage match well together. If you can tell me more about your system I may be able to give you more specific information. Feel free to email me if you like.
