EPS beads vs blown glass mineral vs cavity batts

[SBMS]

We are looking at a brick and block construction with a 150mm cavity. 
 

What experience has everyone got with the above option and can anyone recommend a particular insulation method for a 150mm cavity?

 

At the moment am favouring a blown in product as it’s guaranteed 100% coverage but would be interested to hear peoples thoughts on price and performance?

EPS bead all the way as long as the brickies keep the cavity clean - easily done but they need to be watched so you dont get lots of mortar in the bottom of the cavities. Beads flow very well so you get a decent coverage. 
 

Batts need care when being installed and can end up with gaps.

Would you recommend a particular EPS bead product?

250mm EPS beads here. I would consider batts if I could put them in myself or use a trusted builder.  There's a pretty comprehensive thread here.

Any of the graphite EPS beads tbh are fine as they are all made by one or two manufacturers.
