I'm afraid, I am a creature of habit and use figma too.

Mostly because it's cloud based so that other members of my team can chip in and help (especially with typos!). Unfortunately, its a pain in the butt if you want to export as pdf because it becomes huge.

My trick though is I make (almost) everything with symbols and auto-layout. That way text is always aligned correctly, and it is easy to make big changes.

Other options I have used in the past:

- Indesign. While it's designed for print, it is really nice for presentations and compresses pdfs really well.

- figma + google slides. Google slides annoys the S**t out of me because its really difficult to align anything. That being said, I sometimes set up master slides, then import designs as needed. Once again, it's good for multiple people working on a presentation.

- Canva. I looked into it a long time ago, but was annoyed by how templated it was didn't allow multiple collaborators.

Sorry I can't be of more help!
