Congratulations!
Electronics are a pretty personal item, and these days interoperability and networking is important.
These days, having your chart with a radar overlay is nice, but if I were going to do that, I would go with a pair of identical head units and put chart on one and radar on the other. Split the screen on one of them and have your bottom machine as well. If you get a networked VHF, you can also put DSC data on your chart. Networking is the way to go.
For that... I like Garmin products. Second place, Furuno.
My boat has old school electronics, but everything works and I like what I have.
Chartplotter: Garmin
Fishfinder: Furuno with an Airmar 'tilted element' through-hull transducer
VHF: Icom
Simple and reliable.
