Well, I think all of you know I abhor Windows, so I vote with a resounding, "Nay!"
But... There is always a but, and in my case, a butt.
Get signed up for the download, burn Win10 to however many DVDs are necessary, and put them in a safe place. Win10 won't be free, but for one year, so grab it now, at no cost. Maybe you never use it, but you have it, just in case.
No way would I consider dropping Win7 for Win10. But mind that I do not use Windows, at all.
