Willie Nelson has written some great songs.
Trent Reznor has also written some great songs.

And there you have it. Plugging direct is well suited for straight-forward rock, blues, jazz, country & yes, even P&W.
But it is extremely boring for noise rock, shoegaze, post-rock/hardcore/punk, ambient etc.
THERE IS NO DELAY OR PHASING AND THAT SIMPLY WILL NOT DO.
Certain pedal combinations have been more sonically inspiring, creative catalysts than any amp I've tried by itself.
Tall Font muff > DMM > Small Stone, for example.
Recently, that above combination has directly lead to multiple riffs and blooming, melodic, rhythmic washes to spring from my fingers and imagination.
Furthermore I would never give credence to a paradox of "pedals vs songwriting" because the 2 are anything but mutually exclusive.
But I will stop short of telling someone else what works best for them or what they *should* be doing.
