I am strongly in the "Pour" camp (Hoping to pour one in the near future actually)
If you are going to use a block of concrete to mount a pier it needs to be poured into the hole, if you crane in a precast block then it is inevitably going to settle and move around over time a lot more than a cast in-situ block will. And if you don't need mechanical assistance to lift it in to the hole then you are probably not using a big and heavy enough block.
Nick does have a good point though. I have lived where I am for 18 years and don't have any plans to move for decades yet, but even for me I am looking forward. The piers would need at least partial demolition but the obs plan is for one that is big enough to simply use as a functional shed by just locking the roof down should astro use come to an end.
