Eton College is different to Shaving Chop IMO. Shaving Shop is a cedar fragrance that happens to open with citrus and has some moss in the base. It pulls off the feel of a Shaving Shop because it is so clean and crisp, almost soapy. Eton College is a barbershop fougere, so it is a bit more complex and richer, but that doesn't make it better to me. In fact, I find it a little cloying in its sweetness at times, but then, I hate sweetness in frags so I may be oversensitive to it. St. James is different to either, more contemporary in its feel, almost like someone took a barbershop citrus and overlaid modern aquatic notes onto it. It's okay, but not my preference. I would say if you want barbershop and soapy, Shave Shop and Spanish Leather are very different to each other, but they both do the job. Spanish Leather is more of a cool-weather frag IMO, while Shaving Shop is good year-round but shines in summer when the citrus sparkles a bit and the soapy cedar is like an aura on your skin.
The Sandalwood and Eucris are to me the bookend occasion scents, but as far as the everyday barbershop soapy fragrance I am torn between the GFT Spanish Leather, and TOBS Eton College, Shave Shop and St. James. Strength and Longevity are pretty important though.
Yeah, I know Quinlan. A former co-worker of mine grew up there.
The Shaving Shop cream and cologne smell nearly identical. I haven't sniffed the Eton College cream, but I imagine they're quite close. I would say the main thing to note about Shaving Shop is that the citrus you smell in the cream fades pretty quickly in the cologne, a couple of hours at most, leaving you with the cedar & moss combination underneath.
I like your idea for a wardrobe. Curious to see what you finally settle down with.
