What is the exact(!) difference between:
setStoreId()
setCurrentStore()
Example where the two give different results.
// setStoreId solution
$product = $objectManager->create('MagentoCatalogModelProduct')->setStoreId(2)->load(1);
echo $product->getPriceInfo()->getPrice('final_price')->getAmount()->getValue();
VS
// setCurrentStore solution
$storeManager->setCurrentStore(2);
$product = $objectManager->create('MagentoCatalogModelProduct')->load(1);
echo $product->getPriceInfo()->getPrice('final_price')->getAmount()->getValue();
EDIT: I am getting different results when there is a catalog price rule active on just one of the two stores.
