Mainly depends on which platforms you use. If you’re using Bitwarden on Android and/or Linux, then this isn’t a replacement. If you’re on Apple’s iOS/iPadOS/macOS or are on Windows, you can use this. These are also native apps, unlike Bitwarden’s Electron monstrosity on the desktop.
Bitwarden has been lagging in implementing any consumer features for some years now (custom item types has been on the roadmap for six years and is still not done). Except for secure notes in Bitwarden, I don’t think you’d miss anything else in this app. Bitwarden is spending money and focus on the enterprise, just like 1Password has been. For the consumer segment, neither of these are good enough now.

This is actually the reason why I like Bitwarden. They don't seem to be constantly trying to push unwanted features on me. I've always been a fan of the first "rule" of the Unix Philosophy: do one thing well.
I'll be trying this out, but moving me from Bitwarden will prove quite a feat - especially since it was the best option for me after trying over 10 password managers while I was still window shopping for one.
Electron apps are usually (not always necessarily) sluggish and don’t support native UI paradigms or keyboard shortcuts or navigation. The Bitwarden desktop app is one of the bad ones.
Disk space for one. The Bitwarden macOS application is around 390 MB. For comparison, Firefox is 388 MB. They're usually much worse from a CPU and RAM perspective too.
