I come to bike touring from a backpacking perspective and in my experience my backpacking stuff and methods work fine on the bike. I use the same shelter, a Henry Shires Tarptent, for both.

Within both worlds there are many different sub-categories--length of trip, climate, terrain, budget, comfort level (fear), etc. Some do well with a simple tarp, some need a double-wall domed monster with room for bikes, dogs, gear and cooking, wired for internet. If there were one best tent, there would only be one tent.
