To my inexperienced nose, the original Colonia smells similar to Penhaligon's Castile, so if you've tried it you probably know what to expect. It's a great and conservative scent, but as much as I admire it, it's my cup of tea. The Assoluta didn't particularly impress me, but to be fair I've only tried it on a paper card and after sampling more than a dozen other fragrances. Out of all the AdP products I've tried that day, I've liked Cipresso di Toscana the most. Still have to give my other three samples of the Blu Mediterraneo series a good wearing.
But like others suggested, no point in going by reviews, sample them yourself, even if you end up not liking them, the fun of hunting them down and trying is worth the hassle
