I like analog hardware mostly because of the knobs, but there is also a nice spiritual connection to the sound energy.

Note that a solid-state amp can still be analog, transistors vs. tubes is distinct from analog vs. digital. Analog solid-state amps can make fantastic sounds, but transistors are much better at staying linear until they clip, so the transitions to nonlinearity/distortion are abrupt and the crunchy tone is less “warm”.
