What appears to have happened is that between last time I checked and now, some great tables have been produced. I checked out a video of that Deadpool one and it looks amazing. It's good to see vibrant activity in the pinball space; I thought pinball had died off (again).
Fortunately, this is not (IMHO) due to some corruption in the ranking or declining standards. It's because manufacturers, especially Stern, have really managed to elevate the design and playability of new pins to an incredible level and do so more consistently than in the past.
It's extremely difficult to create a hit pinball machine that's initially accessible, fun to play and yet remains challenging over time with deeper rule sets. Many of the top-rated pins are still the "classics" from the 1990s (TAF, CFTBL, MM, TW, etc). Today's best new machines are still being designed by some of the same people who perfected their craft over time (or those who apprenticed at their knee).
I own a Godzilla Premium and it's popular because it really is just a super fun game and stands head to head with the greats of all time.
But TAF will probably still be my wife's favorite table.
Since I have a virtual pinball cabinet now, as well as some friends who are pinball collectors with dozens of well-regarded, sought after machines - I've played everything in the top 100 (most on a real machine at least once) and IMHO - pretty much anything in the top 50 is worth a play, Also, my personal favorites are all in the top 50.
