Purple vs Gold based only on 20,000 vs 40,000 active protect entries

I'm not that experienced in networking but learning some basics so I can improve the security of my home network. My husband and I get by on just 100 mbs internet, which argues for the Purple being more than sufficient. However, since I'm focused on security, I'm wondering whether an argument can be made to get the Gold for 40K active protect entries. I'm ditching my eero with its secure+ plan, now that I understand the limitations, so I'll save a subscription fee and the extra cost for the gold will pay for itself before too long. Thoughts?
