There are different implementations, all of them standarized:

While imaps (tcp/993), pop3s (tcp/995) and smtps (tcp/587) make use of 
specific computer ports, imap, pop3 and smtp using "STARTTLS" keep the 
same ports that their non-encrypted counterparts (143/110/25) to transmit 
clear text credentials protected.

When/why using one or another? 

Well, when opening ports is not possible (consider a restricted 
environment) or as Wikipedia¹ explains, independency and transparency 
seen as a plus when using this extension.
