What is the best and efficient way if I have a process id to use process report or use process info to get the status of the process

I would go with something like this: docs.appian.com/.../recipe-display-processes-by-process-model-with-status-icons.html

Maybe I didn't articulate my question correctly. 

I have the process id. I want to know the status of the process whether that is still in progress.

There are two ways I have seen this implemented.

1. build a process report and pass the processid to get the status of the process.

2. user getprocesinfohistory(from get process info history plugin) to see whether the last node on the process has been completed.

which one of the above two will be efficient. I see people say getprocesinfohistory was better. 

I would like to know what the community thinks.

In general, I try to minimize usage of plugins and would go with a process report.
