For IPv6, 'alias' will not make any difference one way or another.
Strictly speaking, there is no "hierarchy" of IPv4 addresses.
For IPv4, 'alias' roughly means, "add to the end of the interface
address list," while omission of 'alias' and '-alias' both roughly mean,
"replace the first address on the interface address list."
 You can configure a "hierarchy" of addresses, if you have compiled
your kernel with 'options IPSELSRC'.
