let me compare them for you in short.
people are backing up bitcoin while ethereum is only a pump and dump coin that people buy temporarily to get a quick profit. just check the number of full nodes bitcoin has, this is practically zero for ethereum because nobody is running a full node and they all keep ETH temporary to dump it as fast as possible.
bitcoin is decentralized and nobody controls it you never see anything change with bitcoin without consensus, but eth is centralized and it is being controlled by the owner and a handfull of whales from the start. that is why people are calling it dictatorship
as the decision about eth fork was made by one person and he did it without blinking of an eye.
eth doesn't even have a cap, new coins are being created everyday and market is being flooded with them there are 82 million coins available as we speak and this is already 5.4 times more than current bitcoin available supply. a simple supply and demand rule suggest the price of eth should be a lot lower now.
