We all have things we put up with on a day to day basis, and in some cases an operating system can make all the difference. I considered Gentoo however there are more programs out there that have to be compiled than there are that are binary. So my point being I have stuff to do and Gentoo gets in the way of that some what; I have work to do sometimes involving a variety of software I've never used an as such Gentoo doesn't fit this as I don't have the time. I admit that I did start on Ubuntu not knowing why the he'll there wasn't a magnifier. Short story is I used it for a day (yes a day) as I tried installing Gnome and uninstalling Unity causing dependency hell. For about a month I ran Mint but the taste of Ubuntu was still sour in my mouth and as such I installed Crunchbang. This was as the time truly over my head so I tinkered with it for a few days (without Wi-Fi mind you) and then tried Debian. This is where my brain became bloated, but being a fast learner I had used Debian itself for a good one to two months (counting my time in testing). However it lacked something; the latest and greatest. Testing wasn't good enough for me. Everything seemed outdated in comparison to what was on Mint. Switching to unstable wasn't an option. This is where Fedora shines; it is somewhat a kid between the stability of Debian testing and the bleeding edgeness of unstable. It truly was perfect. At the time I loved to mess with things such as X that would render my system somewhat unusable. This is where Korora stepped in. I absolutely hated having to constantly re-add RPMfusion repositories and multmedia packages. From there on I've used Korora. Never really cared for Arch as I can't really justify the benefits of switching. The Fedora community is unrivaled by everything out there. I will admit that there are issues such as systemd and what I believe to be the NSA's backdoor, SELinux. No distro is perfect, not even your custom LFS system however there are ones that work better than others depending upon their interests and tastes. As such I'm happy to say as of yet I'm trying to make a community based distro in the hopes that Red Hat and Canonical will be more community reprint in the future; I want to redefine user friendly.
Honorable mentions: Debian testing, Gentoo, Arch, LMDE, SolydXK, Fedora, CentOS, Slackware, Manjaro, Sabayon, and so forth...
I really enjoy having choice and such it really is a disappointment that the only security enhancements are made by the NSA and Novell (as far as I know). Although systemd doesn't allow the flexibility of sysVinit, it is becoming a harsh dependency for some packages and as such it does support sysVinit installments.
