I like the donut.com pricing page the best. I like the design, except that it goes below the fold on my computer. Also, I like the grid with check marks that shows what you get per tier. I think the standuply pricing page is a bit industrial. I like the heytaco.chat pricing model the best. I think people appreciate anything simple these days. The donut.com pricing page might have a bit too many options. They might be better served by putting the enterprise option on it's own section below.
