Having done moves, way easier. Even I think it's easier, and I use a more manual 
toolset such as you mentioned. But a single command to move an LV from one PV to 
another PV, without editing boot scripts and such really is as simple as it can get.

The process of creating a partition, creating the filesystem, moving the data, 
and changing at least fstab and maybe grub.conf has a lot more steps, and 
usually requires editing config files as well. I trust I'll never be doing that 
so often I get accustomed to it, it usually means either bad initial 
configuration or hardware problems. Note usually in that.

I just don't like one more layer I have to trust, although I really haven't had 
trouble with it in some years on other people's systems.
