Creed GIT works in warm & cold as does Guerlain L'Instant PH. It sounds like you're favoring a lot of Creed fragrances, so I would highly recommend Creed Bois du Portugal - which I think many shy away from because of its complexity and aura of "formality".
Bvlgari Aqva is a very nice aquatic - the best designer aquatic out there, IMO.
Burberry London is decent enough, though I grew tired of it quickly. It also got a bit sweet on me. Givenchy Pi, if you really enjoy the genre, could be upgraded to a much nicer woody-vanilla that doesn't get cloying and obnoxious.
From Creed, I'd also check out Millesime Imperial - which is great on its own or can also be layered with the aforementioned Bois du Portugal to give you an amazing experience. Best of luck, and welcome
Edit: To answer your question about them being unique - this really depends on who you ask. Bvlgari Aqva is very popular (for good reason). It sounds like you'll enjoy exploring niche houses like Lorenzo Villoresi, Serge Lutens, Amouage, and looking more closely at the classics produced by Guerlain and Chanel.
