NB...this isn't necessarily for the OP...players with good (fast clubhead) swing speed and who create a lot of backspin can ignore!!
Ball speed is approx 1.5 times clubhead speed....however, as few of us rarely get this ratio, then a clubhead speed of 90-100 mph is going to offer a ball speed of around 130-150 mph. Taking 140 as an average, then the ideal launch is going to be between 13-16 degrees.
Too little loft on a driver is a problem, unless the technique you employ to hit the ball gives you a good launch. I can hit a 10* with a HL shaft and get 13-16 degrees....but not every time. A few don't get up, don't carry and rely on lots of run for distance.
On my 12 degree, I might get too much launch (like 17+ degrees) but at least these ALL carry properly and are not daisy cutters.
I realise some players DO get a decent launch every time with low lofted drivers but the "logic" in me suggests it's better to get the ball up every time, sometimes a bit high perhaps, but up and away properly. I think what a player might lose in distance is easily made up by a few% more accuracy and a degree or two too much launch as opposed to a degree or two too little.
