Track preset compressor on insert

Just a simple question on track presets: I’m testing some and can’t understand why the compressor is on the insert instead of in the channel strip. Wouldn’t it fit better? I can’t find any real difference between applying an effect on the channel strip or on the insert, so it’s a bit confusing for a newbie.

maybe the presets are from an earlier version without channel strip compressor

it doesn’t matter that much
make your own track presets…

Ok thank you! So I’ll do mine using the channel strip. I hope it will be simple to backup them
