Which one of these systems would have the best effect on blocking sound from upstairs

Current ceiling is timber framed, no insulation and boarded with 12mm plasterboard.

Option 1 - remove plasterboard on ceiling and fill joist space with 100mm rockwool and seal any air gaps. Fit resilient bars and screw 19mm high density acoustic plasterboard followed by tecsound 50 then another layer of 12.5mm acoustic plasterboard and acoustic sealant around the perimeter.

Option 2 - Cut slots out of current plasterboard to allow fitment of resilient bars meaning most of the current ceiling is left in-tact, layer of 19mm high density plasterboard followed by a layer of tecsound 50 then a final layer of 12.5 acoustic plasterboard and seal around the perimeter with acoustic sealant

Option 3 - keep current ceiling in place, build new timber ceiling frame 25 mm below current ceiling with rubber strip between walls and frame and fill with 50mm rockwool followed by 19mm high density acoustic plasterboard, a layer of tecsound then another layer of 12.5mm acoustic plasterboard and sealant around the perimeter.

I'm not expecting miracles from either the walls won't be getting done, at least not any time soon due to finances. Walls are solid brick and plaster

Building a frame will cost me more head height which I'm honestly not bothered about it it gives me better results.

Impact noise is the main issue which I know is harder to isolate

A you are absolutely perfect

You would never agree with this but you really don't see yourself how I see you. You are patient, kind, caring, absolutely beautiful, cultural, open and honest, not afraid to say what's on your mind or say when you are struggling, an unbelievably good mum, a hard worker and someone reliable and trustworthy. There's no game in what you bring....only an open hand reaching out for connection. There's no second guessing with you because you know exactly what you want.

Maybe this time around things will be different for us, I'm all in 🙋‍♂️😘
