Which is better?

basic_library.ino

#include <DigitalPin.h>

DigitalPin forward(13);
DigitalPin backward(12);

void setup(){
}

void loop() {
  backward.off();
  forward.on();
  delay(1000); 
  forward.off();
  backward.on();
  delay(1000);
}

without_basic_library.ino

int forward = 13 ;
int backward = 12 ;

void setup(){
}
