After a bit of digging, it seems all methods have its own drawbacks:

by-label -> can generate collissions and is not present in all volumes

by-path -> can also change because it depends on the system bus it is 
attached to

by-id -> it seems that not all devices provide an ID

by-uuid -> as we have seen, when formating or repartitioning the device 
it can also change

Well, that said I like Lenny still uses the old scheme "/dev/sdx". At 
least if it changes, I still understand it better than the new udev 
naming :-)
