Pine can be a little frustrating in my opinion because it can be so soft and easy to dent or crush just handling it a little rough, even if your tools are sharp.
Pine can also be frustrating if you live in an area where the humidity is always changing. Pine can swell and contract between when time when the tails and pins are cut and give a person fits trying to get them to go together.
