For the exact same events in SQL Trace, you will get the same amount of events generated, so using a server-side Trace won't make a difference. This is why you have the ability to create complex predicates in Extended Events to filter the events at the firing point, and reduce the performance impact that diagnostic data collection has on the server, which is not possible for server-side trace, where the filter is applied at the Trace level across all of the events, and only after the event has fired and collected all of the events data.
