Is it the most convenient, in some ways because it will keep your programs and data, but that doesn't make it the best. Any time to do an upgrade, you are setting yourself up for problems and issues later on. These forums are littered with people having strange issues due to an upgrade. Don't always believe everything from a biased source.
If you asked every car salesman which cars were the safest, they'd tell you the brand they sell is the safest....but all of them besides Subaru and Volvo would be lying.
For the best possible system, a fresh, clean install with the lastest drivers
is always the best way to go.
