For me, it's one-time purchase vs. subscription. For example, I was happily paying 1Password every couple of years for a long time, and left when they made it clear subscriptions were the future.
This is a SUPER important topic. I don't think Dracula Pro would be as successful if it was a subscription. There's definitely a subscription fatigue going on, and people who invest on one-time purchase models will be able to benefit from that
