Which of these two shall I get and looks nicer/more modern? 
And and as far as staying rust free, are either as good as each other, stainless steel or zinc alloy?
The Blomus is stainless steel, and the Smedbo one says "POLISHED CHROME
Solid Brass Core / copper - zinc alloy. Ideal for the bathroom / no rust problems. Finish: Polished Chrome."
My bathroom is nearly finished, bath is in, shower thermostatic unit in, tiling almost finished. Just the basin, LED mirror, shaver socket and toilet waiting here, boxed up, ready to be installed. I don't want a cheapo roll holder as my last one, a cheap chrome ikea one, did rust eventually.
