Personally, I do not see the advantage of ESXi hosts with LAGs outweighing the increased complexity they might introduce in most practical cases. Take a look at these articles explaining some pros and cons on this debate:

Adding to the previous message, LACP is only supported on distributed vSwitches. The standard vSwitch only supports static etherchannel LAG with source/dest IP hashing.

The dvSwitch LACP implementation in ESXi 5.5 supports a large number of different load balancing modes, see these articles for details:
