Just finished Yuri!!! On Ice
I gave it a 5/10 on MAL, and I felt that was being generous. I think it was a very overrated one overall, that said, there were a couple of good points to note.
It does portray a professional sport very well, in terms of showing the competetive nature of the athletes, as well as the finer details like the sportswear/advertisments/sponsors etc. Also, the actual sound of the skates on the ice is quite satisfying to hear...
It's charater development is noteworthy; portraying a character's struggle with low self esteem and confidence issues was well executed, and the professional relationship between Yuri and Victor is well portrayed.
The MAJOR con for me, is the animation; it's WAY too inconsistent for me. I'm not really keen on the overall look of it anyway, but some of the animation, particularly towards the end, seems rushed. I'm not 100% sure if the skate scenes are rotoscoped, but whilst they do show the moves acurrately, the animation of the sequences looks very jerky.
It's a comical anime, so needless to say, the animation often reflects this in typical anime style (sweatdrops, chibi-outs etc), however, it seems way too out of place when you consider that the skating scenes are done in a much more "realistic" way since they try to represent an actual professional sport. Yuri in particular almost looks like a different character altogether when you see him full-out chibi compared to when he's on the ice.
Also, it could be very cringey at times, [INLINESPOILER]especially when the skaters would recite their inner monologues to themselves whilst performing (another bug-bare; there's too many inner monologues in my opinion)[/INLINESPOILER]. It's a bit over dramatic for me but I guess it gives an insight into what goes on in the minds of a professional figure skater when performing.
Overall I'm glad I took the plunge - it was an experience for sure and I'm more than aware of the "you win some, you lose some" in the anime watching game 
Not sure if a spoiler was really needed but I thought I'd err on the side of caution. I'm not giving away actual lines or important plot twists but, I just want to try to be considerate ^^
