How L2/L3 Etherchannel does Load-Balancing

Considering the diagram above ,  assuming that there are many PCs in 192.168.1.0/24 network and many PCs in 192.168.2.0/24 network
What is the best method to choose for load-balancing in this case (Source-Destination IP, Source Destination Mac,etc....) ?

another case is , Let's say in network 192.168.2.0/24 there are separate servers  that procide services to  PCs in the network 192.168.1.0/24
in this case what would be the best Load-Balancing Method ?

Thank you

In both cases IP to IP would be most appropriate as your MAC addresses are always going to be the MACs of the routers jsk.  If the EC connections where switch to switch to host then it would be best to use MAC to MAC.

I agree with atlas_shuddered, normally you'll always want to do ip to ip unless everything is on a local layer 2/3 network and won't talk over a router.

OK ...if we have eliminated the Routers , then Load -Balancing on Mac address would be the best method ?

so, for instance, if client1 sends traffic it will go over  link1
if client2 sends traffic, it will go over different link
and so on

Theoretically anyway.  The algorithm will make the determination of what traffic goes across which link.  Base is round robin but it is offset by load so this can diff the traffic as individual links are loaded.
