I think the responses on this thread are the perfect evidence that there's no "right" or "wrong" answer, just one that's right for you.
Thus fasteddie likes soft saddlebags, spiderman doesn't like top-loaders, and I prefer top-loaders. When I bought my Versys in May I knew I wanted hard saddlebags, but I debated long and hard between the Givi V34 and E21 options. In the end, I went with the E21s and I have since been very glad I did. I owned one other bike with side-opening Givi bags and have ridden many more. But I always worried about them popping open, especially when fully loaded. With the top-loading E21s, I don't worry about that.
I prefer to camp when I'm on the road and I have taken two multi-day trips since I bought my Versys. On the longer one, I carried my sleeping bag, pad and tent on the passenger seat and gear/tools/clothes in the bags. On the shorter trip, I took less and and put the tent in one of the bags.
Either way, if you pack appropriately, you can still use the top-loading bags while carrying camping gear on the passenger seat. But this may not work for everyone, I admit. I'm a minimalist camper.
Which brings us back to my original point. It all depends on what works for YOU.
