Not really sure what you are expecting to hear here when asking for the best update with fewest bugs and security update issues. My advice is, always has been and always will be to download the latest version from Microsoft, or an authorized MS partner distributor. If you don't get the latest, you will need update to it. So I don't see any difference. With over 30 million lines of code, and over 1 Billion W10 systems out there, essentially each and every one being unique, there will always be "issues". But it is important to understand the occurrence and frequency of those issues are vastly and significantly less in numbers and severity than all the hype would have us believe.
Remember, even if 1/10th of 1 percent of the users had problems (and it is no where near that!), that would still be 1,000,000 upset users. And 1,000,000 upset users can make a lot of noise, especially when amplified and repeated over and over again by Microsoft bashers and those in the IT press who simply parrot the same story over and over again.
If want to minimize your risk of being a victim of bugs and update issues, make sure your hardware is compatible with W10 first, install the most current drivers for your hardware and update your installed applications. Then install the most recent version of W10 and LEAVE THE DEFAULT SETTINGS ALONE!
Are you currently paying for extended support for W7 through a volume licensing program? If not, you should have done this W10 upgrade long ago as W7 support ended last year on Jan 14, 2020.
