Should I upgrade to Classic or stay with Core? I can't decide what to do. I am scared to get on the worng version. What is the good version?
Right now they both are compatible, but if Classic becomes the dominant client then you'll need to switch (unless Core also makes a change to 2MB blocks). If Classic reaches the goal of 75% of blocks flagged as Classic, a 28 day grace period will activate allowing all uncompatible wallets/nodes to upgrade before 2MB blocks are active.
How many developers are working behind the scene on Core compared to Classic? If you find that answer, you will know what route to follow. I have seen a detailed road map and simple explanations on the way forward for Core and very little information on Classic.
You have to make up your own mind, but I would much rather back a stable team, who are consistent and goal driven, than someone who jumps from one implementation to the next. < Insert Gavin here >
Classic actually released a very detailed (and well thought out in my opinion) roadmap. Maybe you just haven't seen it?
