JavaScript OData RESTEndPoint DataOperations vs Plugin Reliability

All,
We have few JavaScripts that use RESTEndPoint DataOperations to modify fields on Account and Contact entity from commandbar. I think OData RESTEndPOint DataOperation works Asynchronously.
So is it better to use it or fire plugin from commandbar?? What i mean is is there any advantage/disadvantage of using  OData RestEndpoint vs Plugin ??

Thanks,
Nick
