I built a Pulsar XP and a Zenith 701. Big difference in parts count. The composite Pulsar fuselage is just 2 pieces bonded and glassed together. The aluminum Zenith has several dozen detailed pieces that have to be attached with hundreds of rivets. The Pulsar wings have 17 bonded ribs per semi-span with no fasteners on exterior so smoother air flow. The Zenith has hundreds of rivets for the skin sections to ribs attachment. Each design has different mission purposes, the Pulsar for cruise speed, the Zenith for STOL.
If you don't have plane building experience, take the EAA classes for your potential construction type. Or take the classes to see which construction type you feel more comfortable with.
