Which steam deck for msfs

I want to buy a stream deck, but don’t know which one to get. Which is best? Mk.2 w 15 buttons, plus with 8 buttons and 4 dials, or the monster with 32 buttons!

I have the 32XL and once you start using for MSFS you realize you need all those keys. And if you use premade profiles, you’ll find that is the most popular.

I use an XL and a Plus. Start with the XL (you will want the 32 buttons) and get the Plus when able. The Plus has four encoders to control altitude, heading, VS, etc. A real game changer.
You will need Axis and Ohs (or other interface software) to have full functionality. AAOs for FS 2024 (version 4.50) is available now.
You can get all the profiles you need to get started on flightsim.to.

I also have an XL and a Plus. Having both is very useful.

I use spacedesk with 4 iPads. Touch works fine.
