Well, I guess we will agree to disagree. You do it your way and I'll do it mine. In all the installs I've done I've yet to have a problem with it, and I'm pretty confident that it will stay that way. Sure, soldering and crimping will give a better connection and look cleaner, but I believe twist and tape (alot of tape) is just fine too.

edit: And yes I take pride in my work, just not things like head unit installs... any random kid could install a head unit, thats like taking pride in making it to work on time today.
