Hackers in 5th Edition, Decker vs. Technomancer Options

[SincereAgape]

Hi everyone, it has been awhile. I just recently flipped through the 5th edition core book and ordered it online for a potential game in the next month or two. I have a few questions regarding hackers.

1.) There is a sample battle in the 5th edition rulebook where a decker disables a gun of his attacker. This seems really powerful to me. For the intiative of this particular action (disabling cyberware, weapons, or another device), would the hacker act on their matrix initiative or on their regular initiative?

2.) Hackers in 4th edition seemed much more powerful then Technomancers in 4th and 4thA, at least at character creation with the Technomancer having the potential to catch up as they earned more karma. The matrix secton of the book is something I might not be able to look into the end of the month, so does this hold true in 5th edition? How are Technomancers able to hold up compared to a Decker.

Your help is appreciated.

Cheers!
