Dulux light and space vs silk paint

[OrchidFlakes]

Anyone used both light and space and silk on walls - do they give a similar finished result?

Light and Space is £5 per can more than regular emulsion and I'm wondering if silk would give us a similar effect for less, or is it just going to look weird and shiny....?

Not the same result. Light and space is mat, satin is weird, shiny and strangely seventies.
