ethereum attained its best peg of BTC:ETH of 1:12 in may 2021.. and since then has been sliding down to over 1:35
ethereum is losing and will continue as its underlying cost of minting coin has dropped from near $1k to just $50, meaning its $4.8k ATH was a 5x of underlying value(somewhat inflated).. and now at $2.6k price its sitting at a 50x of underlying value(hyper inflated). so has a long way to fall

bitcoin however is holding strong and not inflated. its sitting at just 1.5x of underlying value. meaning btc has less chance of massive crash but alot of potential to rise
