Forensik Setup

What is the best setup for forensical tasks?
That's sure not an easy question and there will be not "the one and only" right answer, but you can find a lot of good answers to it.

•  the OS:

on the whole you have the 3 "big" types, windows, mac and linux.
so the first step is to dismiss mac, because i realy don't like the apple stuff.
ok ok i admit it - there is no second step, because for me there is only 1 acceptable OS and that is Linux.
Although i have to say, that this is the first time i feel a little disadvanteged by using linux, because there are tons of well known forensic programs only usable on windows. (Don't know if wine would do the job?)
But as always i prefer open source and rely on it! I believe that there is an open source solution for every task and every problem :)

•  the distro

for my daily usage i have ubuntu with the i3 wm (love it), but i wanted to have a little bit more special and of course it would be nice to have the most importand tools preinstalled.
so for me there were 2 options:

1. kali linux:  mainly for pentesting, but it comes with a decent number of forensical tools with it. I had it already running in dual-boot with ubuntu on one of my laptops and did a few ctfs with it. So you could say i have a little experience with the main tools (nmap, hydra, patator, vega, burp....). 
2. Sans SIFT: After a while googleing i found this toolkit (so it is not realy a independend distro) and decided to try it. The installation was very simple, just follow the instructions on https://github.com/sans-dfir/sift-cli#instructions . So i have installed it on a virtual machine (a nice and especially safe way to test) on a ubuntu 16.04.

so much to the setup, i'm going to try the first steps with the Sans SIFT and hope it will work out :D
