I had a spoon (and im definitely in the skinny arsed dudes camp) and it cut me in half.
Its simple, is no such thing as comfortable or uncomfortable saddle, its your arse and its different shape to everyone elses on here, so try a few and see which works best or stick with what you know.
Longevity wise, SDG's and WTB's have always held up pretty well for me (i use Devo SLT's almost elusively now on any of my bikes im planning to sit down on!) tried a couple of Gobi's (new and old shape)but never kept them long enough to be able to judge this as they were both pretty rough on my arse 😀
