Audio Interface or Line 6 pod for home recording?

Greetings...and welcome. 

I use  a POD 2 and a simple interface for my guitar recordings. 

On my web site, you can see picture of the studio set up and listen to the music that comes from that studio rig. I don't like the software based amp sims. I prefer the POD.  or a miked amp.

hi i am a noob to the site.being a guitar player i feel it near on impossible to get any sort of feel without the sound i can hear.

I know what you mean.
I usually record my amp with a mic, but since I moved to a noisy area and don't want to record the sounds of the cars going by, lawn mowers and weed eaters and kids playing or drunks yelling, I bought an amplifier with a line out, the Fender Musiang I. It works pretty well and i can dial in the sound I want easily and record it.
But, if you have a good audio interface and have it set up properly, you can plug the guitar directly into the interface, add an effect to the audio track, click the Input Echo button, and hear the effect as you record.
The beauty of doing it this way is, if you decide you don't like the particular effect you heard while recording, you can delete the effect and you'll still have the non-effected guitar track and you can try out different effects until you find the one you like better. And tweak them to your preference.
Once you record the sound from an amp that's effected, you can't remove the effect from the track unless you delete the entire track and start over.
