What's the better option? I'm generally curious as I've used Line 6 products in the past and have been generally happy, though they usually have something fail a number of years down the road.
ok, to be 100% honest, i have second-hand info from technicians who cite line 6 as the most common and worst sounding guitar gear. but as they are professionals, i trust them .. however i have never used one myself. i have used other all-in-one preamps / digital effects boxes and have always been disappointed.
now, for recording, you really just need the I/O box, which generally preamps as well. you might want to add your own preamp as they "make the sound better", but i prefer to work with a line level and add effects from my DAW.
generally, the industry standard for input boxes is the M-Audio 2x2. it's cheap ($100) and completely noise and lag free.
for effects, i would recommend a minimum of a specific pedal for each. even the much maligned BOSS are actually pretty decent.
now, digi pedals such as the Zoom, or Line 6, generally sound ..ok .. if you keep the volume low; if you turn it up, you'll see that they mangle the sound. If you are exiting to headphones, you'll probably not hear it, but plug it into a marshall and you'll see what i mean. And they disappear in the mix.
honestly, i recommend anyone who wants to play guitar, to just get a job, and buy a fender cabinet. $1200 one. it will last you for your entire life, and the Twin Reverb are super-versatile. Both the preamp and the equalizer can be set to any setting and they will always throw out a good sound, and they change dramatically. Essentially you have at least 4 totally distinct tones to work with, and then you can use the DAW to fine-touch it.
