How heavy is your planned load?
Most modern disc frames (including the two you mentioned) are stiffer than many loaded touring frames from the 80s/90s by a factor of at least 2. The Breezer Radar is an excellent frame and is not noodly in most normal use cases. The frame and fork are designed for up to 29x2.2" tires which means they have been designed to pass strict European testing standards above what a typical paved road bike would be held to. This means shorter butted sections, thicker tube profiles and relatively high stiffness.
The next step in stiffness is going to MTB size steel tubes, double oversize which is ~31.8mm TT and 35mm DT. As well as 2OS+ headtubes and steerers - 1 1/4"+ compared to normal 1 1/8". This is a ton of bike for paved riding, most non-technical singletrack, and is probably not what you are looking for.
I would recommend you test ride some bikes and determine more of what you want out of your frame and what "noodly" may mean to you. Online reviews are generally a poor starting point, especially when building from a frameset.
