Miro

Pros

- Ease of use is stunning. It's so cool how native is your experience with the editor - they detect the touchpad and optimize editing for that. Awesome!
- Pre-built templates helps to start conceptualize, instead of bothering with bells and whistles of graphics
- The endless board is amazing - you can keep lots of stuff in different forms (mind maps, hierarchies, Customer Journeys) that is related to the same thing together.

Cons

- Sometimes "clever" positioning of elements works not in the way I would expect, but I guess it's something I just haven't got used to. I suppose it's rather minor inconvenience.
- Guys, you have to do something with your onboarding - it's way to annoying for people, who just logged in to view the board someone invited them to. I would need to click away from 3 pop-ups to just see the board. If you manage to fix it - your tool will be perfect!

Pros

It's great when your team is out of reach and you need to gather some ideas. It works even better than the physical presence of people, because it forces them to put it in a note - you can organize notes, transform them etc. Also, you can even see where everybody's mouse cursor is, which, even though isn't required, gives you a nice feeling of collaboration (imagine 10 cursors flying around, doing stuff... it just feels powerful and stimulating). Of course, you can turn it off if you'd like to.
The collaboration board is 'near-infinite', offers many types of objects (stickies being most popular, but also tasks, lanes, images etc). There's meeting agenda, todo list, and other stuff you might need from an online meeting tool.
Paid version also gives you an option to use active elements, like voting, countdown timer etc. Very cool.

Cons

The history of changes isn't that easy to track - who did what and when, who's put this element? when? what was added by John? etc.
What this tool doesn't offer is an actual meeting (call/video) - for that, you'd have to use other means to connect.

Pros

Graphic solution for sticky notes is almost perfect and realistic it is pleasure working in Miro Boards.
Shared screen does exactly what is promised, my clients just have to click on the emailed link in order to join my board.
Video and voice options related to mapping software are probably the best value for money at the moment on the market.

Cons

Blurred view when is zoomed out and turned the image into an aerial view, to be more precise, I have to zoom in to the sticky particular sticky notes in order not to be blurred view which makes concentration high on the board instead on the idea which is discussing among the participants.
I'm not the happiest about the solution for lining up sticky notes, the Lucidchart offers somehow better solution.
There could be a template for House of Quality or QFD with formulas, I would pay some extra penny :)

Pros

Easy to use, excellent real-time capabilities

Cons

Poor customer support & dishonesty. The change to Miro saw them stiff paid Premium users of Realtimeboard and not honour the remainder of their subscriptions
Slow pace of feature development
No offline capabilities

Pros

The idea of a shared whiteboard is great and well executed in Miro. Everything you do others can see and can interact with in realtime.

Cons

Kanban boards are rather bulky to handle and the idea of placing them onto the board is sort of contraintuitive, but it works.
