Question Baltics Trip: Fly Direct into Tallinn or Take a Ferry?

I am planning a Baltics trip this May, covering Tallinn, Riga, and Vilnius. I'm torn between flying directly into Tallinn or taking a ferry from Helsinki. I've heard the ferry ride offers stunning views, but I'm not sure if it's worth the extra time compared to a direct flight. Has anyone done both? Which option would you recommend for someone looking to balance convenience with a bit of adventure? Also, if I do take the ferry, any tips on making the most of the journey?
