I’d prefer to use fewer tools instead of many, so I tried FigJam for some things I normally use Miro for and it mostly worked, but some stuff was a bit too lean.
If you pimp out the current features a bit more (save custom colors, change outline color, change line width, create custom labels on post-its and add some stickers, emojis and some simplified illustrated people/figures for personas etc.) I think you got yourself almost a fully fledged Miro replacement - Miro is nice, but imo a bit too much and I going all out with “more is better” attitude and I kinda like this simplified version Figma made.
And please try to find a better placement for all the hover options, they get in the way all the time, somehow they don’t in Miro - just steal it.
