The main reason was I had 2 filing cabinet drawers filled with paper and wanted something that could be relatively hands off. I was able to do double sided paper and load multiple pages at a time (24 pages before it didn't work well) so it was easy to burn through the them. I've tried a scanner app before for one off things and have had okay success with them. I guess now the backlog is burned down I can compare the two for things that are just a couple of pages.
