The new normal of international shipping using national post offices is definitely worse than the old normal--slower, with less (and less reliable) information in transit, and less assurance packages will reach you (not to mention a much longer wait before you can reasonably conclude something's lost).
Since the middle of April, my experience with a dozen small packages (equally divided between pipe-related and expensive books, and sent variously from Germany, France and England), suggests 30-35 days is new transatlantic "normal" to New York.
Two packages out of twelve (both untracked) were lost.
Customs processing both outbound and inboard, more often than not, involves blackouts of anywhere from 4-7 days to a month (the latter seems to be the standard outbound delay for whatever DHL service is used for Esterval's "bargain" €50 shipping rate).
And finally routing can be utterly bizarre (now, instead of JFK only, I've had packages routed via San Francisco, Chicago, and Newark too), with some packages receiving inexplicable weeklong sightseeing tours through post offices in the South and Midwest after clearing US customs.
In sum, obviously any private sector carrier is better than national post offices right now, tracking is essential, and if you are able to postpone a purchase or find a domestic source, that's probably the prudent thing to do.
Unfortunately, with all my own international purchases--even my tobacco order from Esteval's--I was buying something either hard or impossible to buy here, and often one-of-a-kind and/or long sought. And, moreover, I wasn't calling the shots. For some of the people overseas I was dealing with, even dropping a package at their local post office was a huge big deal, and I felt they were doing me a tremendous favor.
One other suggestion--applicable only to anything precious purchased on eBay--do use all your persuasive power to convince sellers abroad NOT to use the Pitney-Bowes international shipping "program." It's jawdroppingly expensive and glacially slow, they often carelessly repack valuable things (which they insist on "inspecting"), and if they fail to damage or misplace them, they may exercise, at the sole discretion, an option to confiscate any item deemed to violate Ebay rules (without any explanation or recourse to either you or the seller). A third completely irreplaceable purchase I made perished thereby.
But of course this isn't they only way that I think the new normal really totally completely sucks.
