Track out to Bus vs Send to BUs

Hi :) I am curious about these two different ways to bus things. Here is a scenario: Currently I have four guitar tracks (each with their own amplifier in the track's FX area), and all of them have their track out going to a bus that contains an eq and compressor, and then that bus goes to master. Would it be better for some reason to use the sends to go the bus instead? I guess I'm confused about the difference between the two in the case of application. Thanks in advance for the help!

Compressors and EQ tend to be used as processors rather than effects. The difference being a processor normally affects all of the signal, i.e. no "Dry" and an effect uses a blend of "Wet" and "Dry".

So an effects buss would normally be set up as "Send". If the buss is for EQ and Compression it would make more sense to use it as an ouput, although whether you'd want the exact same compression and EQ on four different guitar tracks is a completely different matter. You'd have that even if it was set up as a send though, but of course you could mix the "wet"  and "Dry" together.

I normally use compressors and EQ on instruments on a per track basis. i.e. Track Prochannel or FX bin rather than on a buss.

Sometimes if you boil these kinds of things down to their basic- it sticks better
Assigning a track to a bus is adding it into the track's path
- a series path.
Adding a send' is adding a second path- a split off the original. You now have two paths
- parallel paths.
