Zar.gg is by far the best if you're jungling, and it's not even close. The profile data on their app is bad at updating, and it can take a weirdly long time (even an hour or so) for matches to show up in your history, even when all other apps show it already. Would be my number one if it weren't for how poorly their builds import, and the fact that their builds tend to clash with u.gg and lolalytics, which shakes my trust a bit. Their charts look the nicest, and the standalone app is so clean looking. Mobalytics has by far the best presentation. Also you have to use Overwolf, which sucks so bad. I can't click into peoples' profiles in the overlay without risking the app becoming completely nonresponsive until I reboot it. My main issue is how inflexible the builds/runes are in the app, and how the profile browser feature constantly freezes the app for me for some reason. The player tags are extremely helpful compared to other apps, and I feel like it gives me a legitimate edge. Especially since you can get all of that info just by hovering in the overlay, without having to navigate. Being able to see someone's LP history at a glance, along with how they built their champs in previous games is so good. Porofessor has the best player research features, and it's honestly not even close. Blitz feels like it has the most accurate builds, and I like how their items/builds import the best, since they show the build path in a far more detailed way.
