ECDSA is a lot computationally cheaper for the same strength. Switching from RSA to ECDSA TLS certs can have a significant impact on the CPU usage for, say a reverse proxy. (By extension, costs less in terms of money and environmental impact). That being said, I do think that global monoculture and putting all eggs in one basket as a society is a bad idea. If you're willing to take the cost and prefer to use something you understand - by all means do so, as long as you're aware of the tradeoffs you're making.
