What do you mean by which is better? Be more specific please. What I can tell you is, they both have awesome warranties(or so I hear). I personally own an Echo Sr switch rod, and I love it. I just wish I had bought a 7 or 8. I wouldn't describe the Echo as a fast action rod, and it really bends to the cork, which I like. It has decent hard wear too, but I wish it had snake guides... I talked to a few people who fish a Cpx, and they all love them. The Cpx is definitely a fast action stick. Different strokes for different folks. Its all preference. I highly suggest you look into the TFO Deer creek switch rod as well, I've cast one, and they are really nice sticks. Again, awesome warranty, probably one of the best!
