Raymarine C127 vs E97

[Fightin Irish]

Just looking for some input on a chartplotter/sonar unit. I'm looking to spend around 3,000.  Does anyone have the newer style units. I also looked at the lowrance 12inch gen 2 unit. I also want to be able to add on in the next couple of years to upgrade my radar and or thermal camera. Does anyone have the down vision or side vision sonar and if so how does it work.

I have the C120. about 5 years old.. Love it
