Quill with all standard sized steel tubing. (unless you like ahead, and want that)
Ahead with oversized tubing, alu or carbon or anything at all 'performance' looking. (pretty much anything else)
I've had a front loading quill stem, Cinelli frog, it looked a bit weird so I got rid.
Much easier to keep bits paired, stems and bars, also saddles and seatpost, always keep those paired too.
Cool, sorted then:
