Well, if you can splurge, Switzerland is the place to do it! The Palace is expensive but considered superb; especially with a lake view room, although these will be even more expensive.
Whether there's more noise around Hotel Schüssel than others is hard to say. Many hotels in the town center are close to restaurants, and terraces may be filled up in August if the weather is fine.
I think indeed Hotel des Alpes is your best option for river view within budget.
