I guess it's difficult to give a straight up yes or no answer here, but here are my thoughts on the changes:
I think after the disasterous ranking-combined system of the past years which practically gave juries the upper hand some change was definetely needed in order to restore some sort of credibility and a feeling that the opinions of millions matter atleast equally to the opinions of a few people (are they really expert? are they bought? what's their agenda?). I'm not a huge fan of the juries in general as most people in this forum already know, but even I understand and agree that something was needed to be done in order to minimize the influence of blind nationalist diaspora voting, so I accept the idea of having juries onboard (but then I don't think the juries necessarily was bringing something better but that's another discussion).
The good: This will give more equal powers to the televoters, which is something I've asked for for years now. Sure the juries might still use their powers to manipulate the outcome to some extent, but not as much in the previous years. I might have added a slight 60/40 upper hand to the televoters, but I doubt EBU would agree on that and I can see some trouble with that too so I guess what has now been introduced is a good enough compromise.
The bad: Emphasis is now given on the juries, while the public vote gets combined in the end and not given as much space in the show which makes it look like this is more a jury-fest than a public-fest, eventhough the audience actually get some more say again, symbolically it looks a bit bad. Also, while it's true that the suspense was killed in previous years when the winner was given pretty early on, I still think there's a suspense-killer in having a result and just in some minutes add the other half and be like "oh here you have the actual winner btw". One idea would be to have the juries combined votes in the beginning instead and then have the spokespersons' give the televoters points from each country and keep the classical build-up suspense like we have now.
Verdict: I know this is another step of the "Melodifestivalization" of ESC, but since the host will give out some 26 points in the end it could still keep a suspense and build up til' the very end (would be worse if it would be less entries), so I'm actually staying optimistic and think this could turn out well and quite interesting in the end. The most important is that viewers will now have more say again, but we still keep juries to even out some things so I guess this satisfy both the anti-jurors and the pro-jurors to some extent atleast. I must say I think I am quite satisfied with the change afterall, we'll see in the final show but I think this could be good...
... for once I can actually say that I sorta agree with a change made by the EBU!
