Using ``++getRecordTypeInfosByName()++`` requires you to pass the Record Type Name. A Record Type Name is a label, which means that it can be easily changed by an administrator. When this happens, the code will simply stop working until a developer updates the Record Type Name. Even worse, Labels are usually translated in multi-language environments, which will again make the code fail.
The method getRecordTypeInfosByDeveloperName() also enables you to get the Record Type Id, but it requires instead a Record Type API Name, which is rarely changed.
Thus it is safer to use ``++getRecordTypeInfosByDeveloperName()++`` than ``++getRecordTypeInfosByName()++``.
