I've touched ROS 2 back in 2019 during the Crystal Clemmys era but it still felt experimental back then (and I believe still was considered beta), I plan to re-evaluate later this year/early 2025 how stable ROS 2 is now.
ROS 2 is better in some aspects that weren't accounted for back when ROS 1 was developed (which started as research platform), mainly distributed systems (multi-robot environments) and good tech developed elsewhere that the system could benefit from.
My personal take is that there is a lot of hit and miss between versions, no guarantee that what works now will work on the next one due to the decentralized nature of the community and the fact the team developing all this is relatively small. I would love to have a way to do small iterations on my own stack to bring it to the latest and greatest ROS release, but the combo of ROS 2 + major Ubuntu upgrade every 2 years is maybe too much for my own peace of mind.
