They have much much better quality, but the resin is usually brittle compared with ABS.

Also it releases fumes that are extremely bad for children. There are quality resins but costing $100 per litter or so.

Today with 3d printers you just can print connectors and connect aluminum beams and wood boards to do whatever you want.

They have today way more advanced options that Legos.
