Worth it? Like anything else, that is a very subjective determination.
I think Philosophy is as good as the one you love using. I have Gingerbread Man, Sweet Vanilla Fig, and Pure Grace Nude Rose in my linen closet 12 months a year so that I never run out -- I love them because the scents are divine, they clean excellently, they suds up abundantly, and they don't dry out my skin.
However, I tried a lot of their other varieties and loathed most of them: Fresh Cream, Honey & Cream, and any of those summer or holiday scents, etc. I will never use these and others again! For me, I either despised the scent, and/or they did not wash clean at all -- they left a smooth, silky residue on my body which just made toweling off a dirty mess.

Good luck!
