Well, as usual, people have different opinions here.
I just started using Haslinger. I have the "spa" version of the Sandlewood scent, which I understand is slightly stronger than their regular Sandlewood. The scent is most certainly there and is very nice. I would rate the scent on mine as about a 6 on a 10 point scale. As someone noted above, scent is not the reason to buy this soap.
Regarding the economics, this is a very hard soap and I understand from folks who have 3017-ed it, that it lasts a very long time. If you are in this hobby to count pennies and save money, then you may have a point (can't really say as I'm not an economist and I ain't counting pennies), but I don't think the folks who love this soap really care about the economics on such a small cost scale.
I personally like this soap for the performance. In my opinion, it is outstanding, up there with Tabac. I found it to be pretty thirsty and when dialed in with a good amount of water, it is very, very good on all the shaving soap factors I care about (i.e., slickness, ease of lathering, amount of lather generated, cushioning, after shave feel, etc.). It is certainly every bit as good as the best artisan soaps I have tried (and I have tried a lot). It will definitely have a permanent place in my rotation from now on. Since I have a space limitation issue in my bathroom that limits me to mostly soap samples, the small puck size is just about perfect for me. I also love how it fits right in my hand when I make the lather-perfecto!
I have not tried the ass soap (it's on my to buy list-Haslinger just happened to come up before that one in my list). If ass is better, as you say, well, awesomeness. But, until I can get me some, I'm gunna keep enjoying this cool little Haslinger puck.
Unless you are the lead dog, the view never changes...
