If you want something standardised use VRRP. If you need rudimentary 
load-balancing usee GLBP. Otherwise use what is supported in your 
environment. Sometimes lowering reachability timer (and relying on NUD) is 
the only solution

If you have to reach as a service point  and/or put in the DNS, use 
static.

Use automatically generated link-local.
