@jakepaint You can do the same thing with Vivaldi by adding search engines and giving them a nickname, but bangs and tab to search are really not comparable. If you haven't tried tab to search, I really recommend messing around with it.
Basically, after you use the search feature on any website, it'll automatically (not manually) learn the search pattern for that website. And then when you're typing in the URL bar, you can start typing the website name, hit tab to bring up the suggested website and then type your search query. It's super intuitive and bangs are not exactly the same - especially if you have to memorize the bangs for each website.
Also it's kinda convenient to not have to rely on another search engine to hopefully have the page you're looking for indexed when you can just go directly to the site you wanted to search
