I dunno that I can really tell any difference. When I first got it I decided I did not like it. I wasnt pulling great shots from it and was having some channeling. I put it a drawer and forgot about it. 8 months later I took it back out and started pulling decent shots from it with no problems and have been using it since. I really can't say why I was having issues with it the first time around. Anyhow, long winded way of saying it is fine, but not revolutionary - at least for me.
Edit - oh yeah, I forgot to add that the reason I came back to the VST is that the shape gave me better clearance from the shower screen with an 18g dose than the OEM LM double basket did. I suspected I was hitting the screen sometimes.
