I think overal Tekla owns the precast market - you can easily create pre-made components for join conditions of steel beams, precast concrete beams, precast walls and precast concrete columns and from all these you can make sheet drawings from all elements seperated.
Revit only gets handy when the design is easy (like rectangular shaped houses). From my experience the biggest problems pop up when the design isn't straight forward (f.e. and entrance ramp for underground parkings, a mushroom shaped column,...)
Keep in mind that Revit back in the days was still only created for architects.
Without any extra paid add-in software, Revit will always lose the battle vs tekla
In general to conclude
Formwork modelling in Revit: easy and fast
Reinforcements in Revit: needs a bit of decent template, else don't even start thinking about using it
Layouts in Revit for concrete reinforcements: big lack of tagging, placing, automation (cfr. detailing basement walls is just a pain in the ass)
