Ufw and Iptables. Which is better and why? [closed]

I ain't afraid of no quake i mean firewall! [ref.1]

TL;DR PART

a simple image about pizza can answer sometimes many questions :)

Take a good look at this picture, then read the text below:

We start from the left (blue means, you have to manage it, green means the vendor/software manages it)

1. Made at Home - Netfilter (Nightmare - Damn I'm Good)
2. Take and Bake - Iptables (Hard - Come Get Some)
3. Delivery - UFW (Normal - Let's Rock)
4. Dining out - Some 1-clicks or predefined setups (Easy - Piece of Cake)

UFW is something like a simplistic interface to get basic things done with your firewall.

How much you want to manage, depends solely on you :)

THE LONGER PART

part I: i found a pretty decent and easy to understand article for the UFW: Understanding UFW

part II: this guide shows you the slight deeper using of iptables: The Beginner’s Guide to iptables, the Linux Firewall

part III: here are informations about the packetfilter, this is the basis of many firewall solutions A Deep Dive into Iptables and Netfilter Architecture

the parts are based on hierarchy, top is dependant on the lower ones.
