Anything Ubuntu based, which includes Mint. Biggest reason? The most widespread use and therefor you'll find the answers to any questions you have. Duckduckgo is going downhill for news stuff because they rely on google's search results but DDG is great for Ubuntu questions and will often give you the answer in a panel to the right of the regular results. More often than not, it will be a slackexchange result as opposes to wikihow who sucks.
You may already know this but Ubuntu/Mint/MX and most of the desktop Linux OS’s are a Debian variant.
For those reading if you are looking for a secure Linux desktop OS I suggest

or SUSE Linux Enterprise Desktop
Run SELinux and chroot the hell out of it. Now this is for security, not ease of use.
