I've got the LSS-2 installed and running on my Gen 3 12 touch. I'm looking at all angles prior to possibly making a switch to bird's or staying with Lowrance. So, what is the difference in these two ducers?

What is the best side scan and down imagining ducer available from Lowrance? When I look at my screens, they are not as crisp as the birds.
Here are a couple of down imaging shots from my Gen 3.
