Differences in getting a model

Question

What is exactly the difference between:

$model = \JModelLegacy::getInstance('Objects', 'MyModel');

and

$model = BaseDatabaseModel::getInstance('Objects', 'MyModel');

Is there some performance differences? Is one of them getting removed earlier in Joomla 5? The communcation and documentation around the Joomla Framework is bad.

I cannot do this yet so please dont suggest:

$model = $component->getMVCFactory()->createModel($modelName, $this->app->getName(), ['ignore_request' => true]);

Answer 1

JModelLegacy is now just an alias of BaseDatabaseModel to support older references to JModelLegacy therefore there is no difference at all between either statement.

JLoader::registerAlias('JModelLegacy', '\\Joomla\\CMS\\MVC\\Model\\BaseDatabaseModel', '6.0');

The createModel() function in the LegacyFactory class, not the createModel() method you have shown above from MVCFactory, also uses BaseDatabaseModel::getInstance
