Same here.
I to fell in love with the White and gold Bismarck so i bought it and it is Amazing.
But my second choice was the Pearlex also.
So if i couldn't get the Bismarck i wouldn't have minded the Pearlex.
Now they are both a little different as you know.
One is shoulderless one is not
One is 5/8 one is 6/8
Both are gorgeous so for me one or the other the white and gold was enough for me.
Or wait and see what the guys here say as they are more knowledgeable than me as i to have only been shaving with a straight for about 2 months **AND LOVE IT***
I think any choice is a great choice for the looks.
As for performance maybe someone knows more if they have both.
