I think curved lines like the stardomes’ make sense and have some very interesting advantages. The “hubs”, which tend to concentrate complexity and cost on “flat line doms”, are simplified, disappearing in some cases.

There’s some disadvantages though. A flexible structure is not always desirable. Bamboo (or an equivalent replacement) isn’t available everywhere. Also, flat-line domes are easier to cover with flat inflexible materials like wood panels. In short: if you have access to Home Depot and no access to bamboo, flats might be easier for you to build.
