As a beginner select the correct path, you should not repent later for not using a good oppurtunity!!!
Mainframe systems are being replaced by the SAP systems. With this itself u can understand SAP has better oppurtunity 😉 there can be some systems left out at the end… For those systems u’ll be supporting…. if u r in mainframes.
Package wise also SAP Consultants earn more. U can opt for SAP if u get an oppurtunity….
