For the last two years i've been using Notability, although for the coming semester I'm going to switch to Goodnotes because of their handwritten and shuffleable flash cards. I will be missing out on the snap features for lines since I am using a custom pdf template. But I'll live.
I also was praying that Google would release a better pixel tablet but to no avail. The current pixel tablet is just too expensive to justify since I would only use it for note taking. (compared to my $250 iPad)
I may look into more FOSS apps but I doubt I'll be able to find one with all the functions of goodnotes.
