For myself, Safari is like Edge. Itās that thing you use once to download your browser. 
I have been using Vivaldi for years now, as well. I was an Opera user back in the day (before the gutted remake came out), and so I was excited to hear that key elements of that development team were starting a new project. It was a bit rocky to start, and I went back and forth between it an Firefox, during the beta days.
My growing dissatisfaction with Firefox formed a similar gradient to Vivaldi reaching maturity, so it all worked out. When Firefox deleted bookmark descriptions, wiping out decades of annotations without warning in a minor update, that was enough. Fortunately I back things up.
What I like most about Vivaldi is that it feels like it is being made by developers that take browsers seriously, as a tool one might need to be productive in. The harder you push it, the better it gets, if you need it. And since it is Chromium-based, you can count on websites working with it, and you get access to most extensionsābut Vivaldi does so much on its own you might find yourself using fewer than you would in another browser.
Settings and data sync are really good. Everything is stored with zero knowledge encryption, and it works well between platforms. I donāt think it is doing anything particularly novel there, but it has a pretty full spectrum data sync, like youād expect from other browsers I think. You can open tabs from other devices, most settings are shared, etc.
The mobile browser is still relatively new, but I donāt have any complaints with it.
Regarding password management, I too dropped 1Password ages ago. For a while I used Enpass, which is a one-time purchase, but I always felt nervous about getting locked into a proprietary system after the 1Passward debacle. So I did some further research, and found a number of open source alternatives that are using what has become a bit of a common format for password storageāmeaning you arenāt tied to any one particular program. Thatās great for many reasons, but one big reason for those that are tied to their mobile devices is that you arenāt having to make a decision that is optimal everywhere. You can mix and match what is actually best for the platform.
KeePassium is one front end for iOS to check out. Itās a solid password manager, doesnāt require any complications to sync (just open your database file out of whatever sync service you prefer to use). It is fully integrated with iOS, so you will not feel any different from using Keychain. I find the free version of it to be perfectly adequate.
Iām not as familiar with macOS software that can work with the KeePass format, but Iām sure there are good alternatives. Iāve been using KeePassXC, which looks a bit out of place (think LibreOffice), but it gets the job done and is cross-platform.
Sticking with open source for password managers seems like a really good idea to me. Having the code out where everyone can see it means not having put your trust into developers to treat your data right.
I have used the DuckDuckGo search engine for years now. At the start its coverage and content were small but now they rival Google plus of course they donāt allow scammers to set third party cookeis.
DuckDuckGo is a privacy wrapper over the Bing search engine, much in the same vein that StartPage is a privacy wrapper over Google. Using a mix of the two can sometimes help if one is returning weak results. More often than not though, these days it seems Google results are garbage and getting rapidly worse.
