All of this really depends on where you are going.
Use it in Europa and you will realize why most people opt for the Hillebergs; fairly lightweight, roomy and very durable.
Most of the prime cycling places in Europe are closer to the sea or ocean so horizontal rain and wind are more of an issue. Campsites are readily available and even mandatory in most countries. Hence less problems finding good soil... but it does happen, especially around the mediteranian.

Most freestanding tents are not an option for me because the inner tents are too short if I lay on my back. Tunnel tents are usually a bit more forgiving or a bit taller in that regard.
If you are average in height however, you can't really go wrong with a regular 2-person freestanding tent like an MSR Elixer or BA Copper Spur.

Don't forget some brands such as Helsport, Nigor, Cause and Eureka.
I love their Wicki Up 3 and would buy a Didis 2 if I had the money.
