I second everything gb1234 said.
I normally fish with part or all of my family (wife, 7 sons, 2 daughters). If you do not have experience being captain on Erie, I would recommend starting around the islands and venturing farther out as you acquire experience. Variables abound and passengers, mechanical devices, equipment and weather all effect how viable it is to fish Canada.
Can the fishing be good? - YES
Does the grass look “greener” ? - On fair water days in summer.
Does my family enjoy fighting rough water an hour in any direction for the chance to catch walleye? - No

There have been times that I pushed harder than my passenger desired, and was left without anyone wanting to go fishing for a while.
If you desire to spend time with your boys, be aware of the parts they enjoy.

I have found myself seining minnows to go perch fishing, chasing gulls to fish white bass, popsicles on Kelley’s, bass fishing near island docks, swimming wherever we limit out, hauling kayaks so the boys can fish somewhere I refuse to take the boat, stopping early so there is time to bow/blowgun fish.
As a father, I would recommend investing time with them outdoors somewhere/anywhere.
