I've an eighteen foot Ionics (residential) pole; carbon fibre, and use an Unger 30 foot pole for higher work.
The Ionics is really good. Light and strong. Recently I had a 'go' of a similarly designed pole, but it was fibre-glass. It felt much heavier.
The Unger pole is good too - strong and light; but I think it takes a little bit of time to get the knack of quickly shortening or lengthening it.
