The biggest thing that I had against using the Pi's GPIO pins were that they're really unforgiving, and only ran on 3.3v. My One-Wire sensor (http://datasheets.maximintegrated.com/en/ds/DS18B20.pdf http://datasheets.maximintegrated.com/en/ds/DS18B20.pdf) Needed 5 Volts, and that's something that the DigiSpark gave me with no issues. I literally soldered pins 1 and 3 to the +5 and Ground pins on the back of the digispark, pin 2 to the I/O5 on the digispark, and ran a 4.7K resistor across the front from +5 to Pin 5 for my pull up resistor -- stupid easy to do and a squirt of epoxy made everything electrically tight.

I've found it's got better GPIO, PWM, etc. options for projects that require them. That, or a put together a nice board that you can plug into the RPi to interface better with it maybe :)
