PipeBlocker has also recently been released to combat this issue, which would be better to use? Or would both be ideal?

As of right now, we probably won't have a comparison chart. We don't have the time to truly compare the two. From what I have seen, the main differences are that they try to block all uses of ObjectInputStream that are unsafe. This can lead to issues using it if not done properly and take into account several different factors. You can see our Technical Approach for that.
