Thank you for your help.
What I have learnt now is,
Layer 3 and Layer 2 etherchannel both aggregate bandwidth. However, the
layer 3 one can only associated with 1 vlan while the layer 2 one can also
become a trunk link. So, it my network is a flat network, using layer 3
etherchannel is better as it avoid the spanning tree problem.

Same technology so what's the difference ?

> If you want to bundle bandwitdh you use etherchannel. Whether you use the
virtual etherchannel interface for trunking or for L3 routing that is a
matter of what your need are.
> If you are talking about design on whether a L3 capable switch be
configured with terminating the VLAN locally or run them through a trunk
port, that is an entirely different question and still depends on what your
need.
