CloudFlare vs Palo Alto – Which Would You Buy?

Any thoughts on which of these two companies you prefer and why?

CloudFlare is not profitable yet, P/E ratio something like 4000, but it's year over year compounded growth is 50% and it's market cap is 20b less than Palo Alto.

However, Palo Alto, seems like the more established company and is quite profitable already, for being only 4 years older. Is there anybody who can give some insight and help me decided on which please
