Hard to say. With that said, why do you want to change it if you're very comfortable with the current setup?
There's a particular stem that I'm interested in and it's only in 120mm.

Get a cheap 120mm stem and try it out. What might feel good on the Turbo can be completely different on a 2 or 3 hr ride.
Yeah. I couldn't bring myself to doing it.
Ended up with what I did want after all.
Great idea on picking up a cheap stem and playing with it.
BTW any reason for removing the spacer above your stem?
Aesthetics. I just really like the look of the cap right on the stem's top.
As far as the longer stem goes, if you feel that you'd sometimes like to stretch out more then a longer stem would be more comfortable, but if you always feel that the hoods are just a bit of a stretch then you wouldn't. Simple as that!
<edit> P.S., if you DO feel that you could stretch more, then going longer instead of going lower is a good way to get more aero without losing power.
