During my career I worked both ACC and TWR. Both have their own rewards. Some people prefer one, some the other.
In TWR there is likely to be more interaction with airlines and airline staff, ACC's tend to be busier so satisfying. Major airports have the busy factor as well, of course.
If opting for TWR then I would suggest making sure you also have Approach, especially with radar, as that gives you more variety.
If money is important then ACC tend to attract higher salary bands.
At the end of the day, only you can make the choice. Both are integral parts of ATC.
