My Advise for Linux Switchers

Package Managers

As I was telling you though there are many package managers, the organised ones are

a) Debian,

b) RPM,

c) URPMI,

d) Gentoo and

e) Packman.

Elimination & Selection of Package Managers

I am eliminating Pacman Series for three reasons:

a) Not for all machines

b) Difficult to deploy and use.

c) Even the seemingly easier ones like Kahel-OS, Manjaro Linux, Chakra Linux and Bridge Linux are not stable on all systems

I am also eliminating Debian Series for three reasons:

a) Broken and Non Updated Package List

b) Weak Security & Comparably Less Stabler

c) File Manager is not capable of handling volumes & hence can crash without proper log.

Thus the three package managers - RPM, URPMI & Gentoo are better Linux Base.

About RPM
Now of RPM we have three great original OS - Fedora, CENT-OS & Open-Suse of which I am eliminating Open-Suse as it is not comparably great. I do not want to go for any derived distributions like Stella, Kororaa, etc., as Original Ones are better and easier to be deployed and used.

About Gentoo

Of Gentoo there is only one great distribution - Sabayon, which can't be eliminated.

About URPMI
URPMI List has four great linux - Mandriva, Mageia, ROSA & PC-Linux-OS (PCL uses apt-get instead of urpmi commands). Of these I have never tried Mageia which is always praised by the Distro Watch as a Better Linux. However I do not vote for it for from the documentation I found that it is mixing Linux Mint and CENT-OS in a unique way and is also forging Mandriva - This means, it's features are more of a concept than reality.

I have attempted Mandriva and felt some instability & non compatibility with it. I found ROSA & PC-Linux-OS to be better OS. Thus my List is Fedora, CENT-OS, ROSA, PC-Linux and Sabayon as the best Linux OS List

Basic Conclusion:

My Choice for Myself

I keep Fedora & Sabayon at same level - these two are my No. 1 Choice and I recommend them for Personal Use & not Enterprise Use. I am planning to migrate to Sabayon 13.08 if Fedora 20 is also sucking like Fedora 18 & 19.

Similarly I place CENTOS and ROSA at the same level and these are my No.1 prescription for Office or Business Use. Though ROSA Can be deployed for Personal Use also, I do not recommend it as it has a bit complicated installation procedure

PC-Linux-OS is my No. 2 Choice for Both Personal & Enterprise Use.

Suggestive Choices

1) Linux Switcher - I do not recommend these for any learned end users; it is just for beginners.

No. 1 : Ubuntu LTS (A Stable & Simple OS)

No. 2 : Zorin (More Windows Like OS)

No. 3 : BOSS (For Patriots as it is the Indian OS) otherwise Linux Mint Based on Ubuntu LTS

2) Learned End Users – These are those having my taste and ability to tweak things for their best

No. 1 : Sabayon 13.08

No. 2 : PC-Linux-OS

No. 3 : Fedora 19

3) Best Enterprise Usage – These segments shall have a learned system administrator to trouble shoot the problems

No. 1 : ROSA Enterprise Linux

No. 2 : CENT-OS

No. 3 : Open-Suse

Simple Summarised Review of My Selected OS are as below

Simple Review of the OS

Fedora
