which strategy has a lower cost stratified sampling or optimization?
optimization require more rebalancing than stratified sampling. I would say that stratified sampling as lower cost.

Stratified sampling = lower cost
Optimization = less tracking error
They should b combined wiith replication for best results.
replicate the largest positions and then use either of these or both to get best results.
