Aquamira for newbies?

Should I get the solid tabs or the drops? Which is easiest to use and lighter to carry? I’m also a bit unsure on how you use it for small amounts of water (1 or 2 liters), like do you need to chop the tab in half or use half drops? Any insight would be super helpful 🙏 I will also be using a sawyer, but want to have two options in case.
