There are a lot of options but somehow Google Chrome is still best option, there are not many reeasons but they are important.

• Ease of use - passwords are stored in one place and you can log into mobile apps using them. This removes need of third party apps like LastPass.
• Compatibility - Chrome is compatible with a wide range of devices, including computers, smartphones, and tablets. This makes it best choice to synchronize your settings, bookmarks, and again passwords across all your devices.
• Websites from Google like YouTube tend to work faster and better on Chrome especially when there are any changes.
• Extensions - Chrome has a large library of extensions that can be used to customize the browser and add features.
• It just works - Chrome is very stable and secure as features they add are carefully tested.

Thanks to Amazon Appstore and Intel Bridge technology you can now run Android apps natively on Windows 11.
It is even possible to install APK files using programs like WSATools.
However it is worth noting that it uses a lot of resources, hopefully Microsoft can fix this in future updates.

Windows 11 is a free upgrade that anyone with active license of Windows 7 or higher can get as long as you meet minimum system requirements.
You may also get the free ISO from Microsoft website to try it out even without activating it.
