I tried to open OXT and search an address, but it doesn't work (Address / tx isn't loading, tried for several browsers. I'll try tomorrow again) Maybe someone else also can't load it
)
Uhm... it works fine on my side... Maybe it didn't work on your side due to a maintenance of the website (which was completed meanwhile)...
Later Edit: I would like to propose now
https://bitcoinwhoswho.com. This one isn't mentioned in OP and it has very interesting features
Added. At first, where it didn't seem very user friendly, I was a bit disappointed but it seems to be an interesting tool. I won't call it explorer *
(I've just taken a random address posted on the site flagged as "scammer address"):
Scam alerts are added (I don't know how such reports are determined)
Yep, this tool is awesome due to this feature of flagging scams. Regarding
how to create a flag, on the upper side of the website there is a button named "Report Scam". If you click on it, a new page is displayed, where you can insert the BTC address involved in a scam, but not just that. And here things become very interesting. Excepting scams, you can also report "Bitcoin Abuse, Scams, Blackmail and Extortion Emails". Besides, the reporting page also offers a link for making a report directly to FBI
Bitcoin Scam AlertsReport the Scam It's essential to tag every scam address so that transactions with it can be detected and avoided. There are no bitcoin police. The community has to step up.
Report Stolen Bitcoin You can report stolen bitcoin to the
FBI but they're not going to do anything unless it's a million dollar scam. By immediately reporting to BitcoinWhosWho, legitimate downstream actors will know when an incoming transaction is tainted and be in a position to act.
Help Make the Bitcoin Commmunity Safer Alert fellow bitcoiners before they become victims and help global law enforcement bust bitcoin thieves.
Why Should I Help? Even if your report doesn't lead to an immediate resolution of your case, you know that it could help solve another case, now, or 10 years from now. The blockchain doesn't forget.

*But we can't view transactions, only Bitcoin addresses can be viewed.
Yes, I observed that now... But you can see though all transactions performed by any address.
Excepting all these, I'd also like to mention that I
updated the Romanian translation of the topic with three new websites added by you in OP: mempool and CoinCap - sugested by SFR10; and BitcoinWho'sWho - suggested by me.
