my 2 road bikes are completely identical (same saddle, bars, frame, fork, pedals, fit) with the exception of the stem which is 140mm x 82* on the race bike vs. 140mm x 84* on the training bike. I figure this lowers me 5-10mm. I like have no reason to change this.
Now the TT bike is a whole other can of worms. Going from TT bike to road bike is friggin weird.

My winter/cx rig is a bit different, but i've gotten closer and closer to the road set up on this bike too.
