Install Windows 10 for old laptop, Is it good?

Hello everyone, my laptop is Toshiba L850 (2012 model) and do you guys think is it okay if i format and install Win 10 or just stick with Win 7?
I try to find the driver in case i want to use Win 10 but unfortunately this model only support Win 7 and Win 8.
Thanks

ps : i want to format because my laptop is kind of laggy right now
