PC Master Race

I'm coming from a Logitech G815.

What I liked:

• low profile keycaps and body;
• aluminum body;
• USB port to plug my mouse into it instead of into the PC;
• backlit;

What I disliked:

• switches (presses would register way before feedback);
• proprietary app for macros, and other configs;

What I'm looking for:

• mechanical tactile/clicky;
• backlighting (through the keycap, as I need to see the keys I'm pressing);
• smaller form factor but with tenkey;
• shipped to and from EU;
• wired;
• US international layout;

What I'd like on top, but I can compromise:

• low profile keycaps and body;
• RGB backlighting;
• aluminum body;
• adult/sleek design;

Usage will be gaming (no competitive) and a lot of typing. Budget is the main problem, as I'd like to spend no more than 100-125€ but can stretch it to 150€ if it means having more criteria met.

What I looked at so far: Logitech, but the prices aren't quite there and I wasn't happy with the G815's switches; Keychron, but most of them don't seem to have lighting that goes through the keycaps?; Akko, seem to have the same "issue"; Monsgeek, seems to be more niche stuff and I can't find a small + 10key form factor.

Thanks in advance!
