Both the branches are equally good. Growth and career development prospects are being possessed by both the branches. You can go for CSE as digitalization and Artificial intelligence is on its boom. You will be able to earn handsomely well in future with this branch. 

Hello,
As you have asked to compare between the two engineering that is the computer science engineering and the mechanical engineering so in my opinion that the computer science engineering is a best engineering because the thing is like that it is going at an level on an increment that the mechanical engineering is not .since the placement and also is getting decrease in the mechanical engineering as compared to the computer science engineering so I would like to suggest you that you should go for the computer science engineering the thing is like that. if you are interested or if you are flair with the programming skills, the the small basic, the titbits of the HTML and all languages so you should prefer to go with the computer science engineering otherwise you can go for the mechanical one also.
Thanks

Mechanical do not has much job opportunities.
