I probably played the polar opposites in back to back years, i was with an original Ping G10 driver, had it reshafted with a ProForce V2 x-stiff golf shaft 77 grams. That driver rocked, it was basically aim and fire all day long. Slight curve, miss hits were good, lots of carry, it was honestly a very good driver. but i reshafted it because the light golf shaft, i couldn't feel in my swing.
But there was one problem, i like to hit cuts and fades, and i wanted more feel in the golf club. That's why i went to a Titliest 910D2. Also because i had a 910Fd fairway wood, and needed the adjustment tool ;). I went with the stock Mitsubishi Dia shaft, pretty heavy shaft, Stiff flex. It's just a monster driver, i gained a bit of distance on center hits, lost a bit on off hits, but i can curve the driver. I can hit a 5 yard draw, up to a 30 yard draw. This one hole on my local course, OB left, and i just pound the driver over the trees on the right, and draw it back to the fairway, its about a 15 yard draw. My ping made that hole a lot scarier, because i had to aim closer to the middle of the fairway and hope i didn't pull it.
But when i look for a golf club its this order,
1) appearance, i could probably get use to a white driver, but i like a more classic shape golf head, not huge tear drop, or square
2) stock shaft options, i rather just not have to spend the money to reshaft the golf club or upcharge. Titliest always had the best options for me to fit my swing. But my 2nd most importance is getting the right shaft to fit the swing. Really, all clubheads are very similar, some will be able to work the ball more, other's not, but they are all near 460cc's with a near legal limit on COR's. New materials have been allowed to lower clubhead mass, look at Nike, they basically took nearly half the clubhead mass off the back of the club. But the biggest thing now is adjustability and fitting. Even ping is offering adjustable options, that's saying a lot, ping is usually no fuss, blue collar driver that just works.
3) Loft, basically this you want to match to your approach angle, and the kick point of the shaft to get the spin in the right area. For me, i took my 9.5 driver down to a 8.75 driver, it cut a good chunk off the backspin, really added a bit more distance and workability as well.
Apperance -> find the right shaft -> tune in the loft to maximize launch conditions
