Ableton Live 9 to 12 - What did I miss?

I’m getting back into amateur (hobbyist) home recording, instrumental songwriting, and production. I currently have Ableton Live 9 Standard. How far has it come since then, and is Ableton 9 upgrade worth it? If so, why? And which would you recommend (standard $159 upgrade vs suite $379). (Again, why?)

I know I’m in an Ableton group, but there’s always the Logic Pro alternative, as well.

Thank you!
