I'm a member in all the alliances, and granted, as I'm not very loyal to anyone I might not amass the points as fast as if I'd stuck with a single network. But my experience is this - there are no real benefits to be had. During my years as Bronze, Silver, Gold member at various, I've never once been upgraded. I've never been allowed into a business lounge on the shine of my membership card unless I also had a business ticket. So staying loyal is more of a mental comfort blanket, I think. It doesn't really pay off. Maybe other travellers have different experiences.
That's why I always suggest to go direct, no matter who the carrier is. Taking the long way around with connections and partners, will give you very little benefits and all headaches.
