I love my Simrad, but given your goals I would put the most powerful radar array in that I thought was reasonable. I have found the broadband (G3) to be only very effective close in. I would also buy all of my equipment from one manufacturer to eliminate issues with mix and match hardware. I have all Simrad and for "the money that I had to spend", I think it's tops! It's almost always about the money you have, or want, to spend. All of the top of the line stuff has everything from on board routers for phones, computers, and music as well as all the stuff you need Hard to go wrong unless you are unlucky.
Simrad is available all over Europe, while Si-tex is a no-name in Europe (not meaning bad, just that its not readily available), so difficult to repair or buy.
