The latter works fine in my experience. I do it regularly.

The downside, is that cloning a 750GB drive takes a while
as it duplicates everything including unused sectors.

Things like clonezilla just copy the "used"/active sectors.

A popular way is to use sfdisk. I do not remember the exact
syntax, but a pair of sfdisk commands can transfer the partition
information directly between two drives.

Then use rsync to move the data across.

You may have to run grub setup on the new disk too.
