Question help comparig & choosing between 1X230V or 2X150V transformers

hello DIY audio members
I'm Puzzled again
Whatever amp I'll choose to build, the Transformer to the PSu will be from one of these 2 series of Multicomp transofrmers carried by Farnell :


3 basic questions:
  1. I what ways does the double 115V primary effects performance Vs. a single 230V, if any ?
  2. what are the critical specification to look for when comparing ?
  3. why are the datasheet so different? one specify regulation tme the other specifies only rate amper per second but not the latter(i know theres no connection between the two)
are these completely different beasts ? made for different use cases ?
im biased toward the 1X230 primary as its $20 cheaper.
appreciate any kind of help

the "seconds" is a mis-spelling of secondaries.
The regulation is specified in the voltage open circuit and comes out at 6% to 6.4%. Substantially the same as the 6% quoted for the other.
The temperature ratings are quite good, 180C for the winding and 130C for the insulation.
Shame they have not specified the other as thoroughly.
I suspect the two winding primary version is a slightly higher quality version. But there is not enough comparative data to confirm this.
And it probably does not matter for the resulting audio quality.

Choose the cheaper one.

Thanks Andrew.
that's how i read it too. just wast confident enough.
I've told purchasing mangers and techies more then once:
The most important aspect of your work except dealing with suppliers unreliability is reading between the lines. They write hat they rite for a reason and hide what they don't write for a reason. sift through the marketing fluff and bias. now who know a anyone from another department who has a head on his shoulder and hands on experience with this equipment who can give us some real insight ?
and all of that was said humorously because i was the pisspants rooky who was going to do all the legwork of testing the equipment. but I was always told that I have quick grasp but more importantly I make excellent coffee and that's way more important and Now its time for me to make some more coffee.
