Service Objects - Source/Destination Ports

Question

What is the best practice when setting up service objects, is it better to have Ports match or is it better to have source with 1:65535. Not sure when you use this either. 
 
 Example Port for 443

 OR 
 Source Port - 1:65535 
 Destination Port - 443
