Windows 10 'Upgrade'. Better than 7 or not?

[caduceus]

After postponing and postponing this nagging reminder to update, it started updating this morning, so I restarted the pc to kill it. I'm considering not going for the update PURELY based on the fact that Microsoft are forcing this on me. But if 10 really IS a better, faster, etc, etc OS, then I may reconsider. Hence the poll.
