A quick pic - sorry for the rumpled appearance.
I just woke it up from sleeping in the watch box. 

If it has to be a singular Rolex, this is mine - the two tone stainless steel/gold GMT 2. IMHO, it's dressy and sporty at the same time. The role of "Iconic no-date chronograph" in my collection has been taken by the Omega Speedmaster Moonwatch.

I love this model, IMO the nicest looking 2 tone Rolex out there. The gold Numbering on the dial really makes it POP.
For stainless steel only, in order of blinginess:
Datejust 2 -> GMT2 -> Sub
One of my bosses has the fluted bezel DJ2. REALLY BLING. When I'm speaking to him, the fluted bezel just jumps out and is super shiny. And for most people, fluted bezel= Rolex.
GMT2 is practical, has a nice extra feature. Quite similar to the sub other than the numbering on the bezel and the polished centre links. Another boss wearing this, bracelet pretty bling, but not too over. Definitely noticeable.
Sub is the most boring, common and practical. Unlike the GMT which is hard to set (no quick-set date, annoying & GMT hand also mafan to adjust). Sub is THE man's Rolex, but it's pretty boring lar.
It's up to ur heart, don't settle on "normal". For example I was choosing between the Planet Ocean & Seamaster Chronodiver. Since "the" Omega diver was the Planet Ocean, I was tempted to get it even though I thought it was boring. In the end, I ended up with the Chronodiver because I loved the blue bezel & Chrono function as well as the "bling-bling" bond bracelet. Sometimes love for bling > safe and practical.
