This is the one I am using after my Saitek died. It even came with extra key switches and a tool to help swap them out. It's a gamers keyboard so they expect some keys to get worn out... It is clackity clack, though and that was the only thing I miss about the newer membrane keyboards.

For me, as a novice, my first concern is can I read and understand the code after a good nights rest. After I get it running, then look for ways to make it better. Of course VS2017 does a lot for me. I use inline returns all the time for avoiding null errors when getting data from a DataGridView. But, for compound conditions it depends on what I am doing and whether they can be easily combined. As for the final version with the "?" for me that obfuscates what is happening. But, then I am a novice. In this case I would probably settle on the next to last version.

Most of this activity seems to be tied to a Microsoft Account... I only use Local Accounts, I am wondering how that affects things... Does anyone know?
