Of course it's a better way. More expensive sure, but better usually is. Offset bushings will get you at most around +3.5° of caster. At most. The QA1's should get you closer to +5° if you want it. No to mention less flex, and no 50 year old rusty suspension parts.
And no need for Moog anything, since the quality of Moog parts has fallen off a cliff. And they're the only ones making the offset UCA bushings.
