Not much different than it was from Seasons 19-23... a small handful of solid episodes per season buried in a sea of disposable garbage that you have to sift through.
The most noteworthy changes between then and now is that the actors sound another 5 years older... and it's not too difficult to tell in a lot of cases - especially for characters voiced by Julie Kavner and Harry Shearer.
Episodes seem a whole lot more quiet now. Where in the past you would have heard music cues from Alf Clausen's in-house orchestra - even if they were over-used - now you hear nothing except the characters talking outside of the occasional borrowed track they pluck out of Hans Zimmer's library.
They really like to use Kevin Michael Richardson now. And not in the way they've used folks like Chris Edgerly or Karl Wiedergott in the past where they have a generic character that needs a voice for a scene. More like, "let's create a wacky character for Kevin where he can monologue for a minute and pad time".
We've had more Marge-Lisa episodes in the past 5 years than we had in the previous 23 seasons combined. To be fair, this was an area of opportunity as these were virtually non-existent in the Classic era.
They finally added another woman (who wasn't married to one of the male writers) to the writer's room. That was long overdue.
Matt Selman's been consistently getting 3-5 episodes per season to showrun that inevitably wind up far superior to those from Al Jean. Actual effort is being put into episodes to make them memorable again.
For episodes not showrun by Selman, we've seen some of the best couch gag/openings courtesy of guest animators brought in to leave their mark on one of the most heralded shows of all-time. Here are a couple of the more noteworthy ones...
The animation direction has actually gotten better. Rob Oliver is now an all-time Top 3 director for the show and we're now seeing a lot more expression from characters in scenes like in this case example from Season 28's The Town...
That's about it.
