They are different things so my answer is generally "both".
Every time you add an extra disk the rate of failure of the group
goes up - a filesystem across 2 disks is less reliable than a
filesystem across one.
md makes block devices redundant. lvm lets you manage logical
volumes on block devices but provides no redundancy[*]. Most people
want to do both.
What's your configuration now and what sort of configuration are you
looking to move to?
Cheers,
Andy
[*] While LVM "mirror" mode does let you make a redundant mirror, it
is not a mature solution and does not seamlessly survive a
device failure.
