Compare

Where PingXen wins, and where it does not.

Most uptime tools check HTTP well. The real difference is how many separate products you end up paying for to cover one stack, and what the alert tells you when something breaks.

The short version

Prices are the cheapest paid tier each vendor publishes, taken from their own pricing pages.
