snackeyp, it all depends on the cartridge. With most modern moving coil cartridges a Tri Planar arm will sound better unless some mass is added to the SME. If you set the resonance frequency of both arms to be exactly the same with the same cartridge installed they are going to sound identical. IMHO the SME V 12 is the best arm made for most modern cartridges. When it comes to the Koetsu's and Air Tight's the Kuzma 4 point 14 has to be heard. Best bass definition I have ever heard come from a turntable set up. If you are looking for dependable, durable, well made turntables and arms it is hard to beat SME. If you are buying these devises for looks you are in the wrong hobby. There is an inherent beauty in precision.
