From first principles... most people are trying to emulate a particular guitar sound they have heard on record (if you are trying to construct a revolutionary guitar sound never heard so far in the history of the electric guitar then, DI and mangle but good luck with that!) It follows therefore that the 'tone' peeps are after is usually that from a micc'ed up cab? That throws up many variables. Even if you know the exact make, model and mark of amplifier/speaker* and similarly that of the guitar you are very unlikely to know the control settings used on the amp or guitar. You will also have no idea of the SPL of the cab in the room and the power an amp is working at and going into a speaker makes a huge difference to the tonal quality.
IMHO the best way, to start with anyway, to record e guitar is from a cab with a mic (unless you KNOW "they" did differently) at least then you are in with a slim chance of a "real" sound. Not bass G however. Even if you have a slurpy 600W valve amp and an 8x10 cab, you will set every mortal thing in your room rattling. You may not notice but..."sore thumb" on playback!
*No two guitar speakers sound the same either. Just because 'he' used a V30 or a Greenback does not mean it will work for you.
