Rafael from Crypto Vigilante calls Bitcoin "the honesty chain"...
I think this is a great description. It's strength is it's clear verifiability/auditability and resistance to change in a economic world of deception.
Monero is a shadowy cyber forest that provides refuge from real world adversaries. It's obfuscation/anonymity and adaptability make it a powerful tool.
But both of their strengths can also be their weaknesses.
