Upgrade to Aneros?

Hi. I bought the Spark Ignition PRV-03 about half a year ago, and it’s hasn’t been that great. I bought it mostly because it was cheap, and I was just starting out. The times I’ve gotten the furthest, I haven’t used it.

Now I’m thinking about getting the Aneros Helix Syn Trident.

What do you guys think? Is there a big difference between the two? How would they compare?
