I think that for me, creating the final finish on the body using paint is the best part of building a kit. You really can have some fun with the painting, trying out new techniques and stuff. You can't remove mold lines and sand and fill joints properly if you're not going to paint afterwards. I also feel that an airbrush is an investment every modeller should make. Spray cans are fine. But after a fair few models an airbrush will pay for itself over the cost of cans and you can mix your own custom colours/shades not having to rely on what's available in cans.
However, if you prefer not to paint bodies and stuff then that's ok too and you should build how you want to. Everyone builds differently in the end and nothing is wrong if it's right to you..
