So, barring the odd typo I've come across so far, (gird instead of grid), here's my thoughts.
1) Priority System. Still my favourite system for character creation. Glad to see it back, been enjoying using it, looking forward to how it will apply with metavariants.
2) Mystic Adepts. I like the split between power points and the magic attribute for spellcasting. I've not made mystic adepts, but two of my players have, and this is almost a godsend to them.
3) The Matrix. Honestly? I don't care how much flack people are giving, I like the new Matrix. It makes sense to me, and I could see a number of real-world parallels that made it easier to understand. The description of a number of stuff at the beginning reminded me of a really advanced version of Second Life, which kind of makes sense, and the way everything is laid out reminded me a lot of how cellphone carriers work these days. It made everything structured and codified - which makes sense when the corporations want everything to run smoothly, the Overwatch concept made me grin, and how the new programs, persona, and technomancer rules work will make things much simpler for me. So, thanks for that.

4) I noticed that armour is a single value, and while I've not gotten that far into studying the rules yet, it has me intrigued, and I'm going to be looking at that a lot closer soon. I'm very interested in seeing your 'Augmentation' book for 5E.
Thanks for the book, hope to see a lot more soon!
