whats the best ethereum block explorer for accuracy. etherscan isnt that accurate for older data

im in the process of doing taxes, got pinged for years 2018, 2019, 2020 by the ATO (australian tax office)

with etherscan, for years 2018/2019 the transactions tab often doesnt go back far enough for my wallet; the internal transaction tab where ive withdrawn from a dex has missing transactions tho the transaction has will exist on ether scan it just doesnt show up in my wallet transactions for some reason. same issue with the erc20 token transactions.

Ive had a look at a couple of other block explorers:

https://etherchain.org/ – seems more accurate though it doesnt have utc time just the block number.

https://ethplorer.io/ – this one is nice in that it allows quick tagging of addresses for notes. and seems to be able to tag less comon exchanges like idex better than etherscan.

that said, i do like how etherscan puts the transactions, internal and erc20 tokens in different tabs.

just curious if there is something more accurate / better features then what ive mentioned. big plus if there are block explorers that can identify older exchange wallets like cryptopia (got hacked and taken down, so i have no idea what money i put in and withdrawaled from there)

and fyi, this is why you log your trades. im currently using https://koinly.io to do my tax which is doing a good job so far, but it cant track everything e.g. idex withdrawals and deposits. And yes ive reached out to idex to get the deposits / withdrawals, they told me to look at a block explorer…
