The link between handwriting and higher brain function has been studied a lot, it seems that at least for recall and memory writing things down by hand is very helpful, so it is likely that more neural connections are formed when using actual note cards. Just one random study: https://journals.sagepub.com/doi/abs/10.1177/154193120905302218 (via https://whereisscihub.now.sh/ )
For a similar reason I still take handwritten notes in conferences, I almost never review it but it helps me remember. The whole point of an archive system is to help me find notes when I need them ,so the extra overhead seems worth it.
