What is LAVA vs Pyr?

Could you please clarify the distinction between LAVA and Pyr for me? As a cryptocurrency enthusiast, I'm interested in understanding the key differences between these two tokens, including their use cases, underlying technologies, and potential for growth. Are they competitors in the same market segment, or do they cater to different audiences and needs? Additionally, how do their respective communities and ecosystems compare, and what sets them apart from other projects in the space?
