I have a little bit of experience with both sides of this chart. I own a CAAD12 and three HongFu frames: FM296, FM169, and TM6. The CAAD12 has a BB30A bottom bracket which started creaking with the Hollowgram SI crank after about 1,500-2,000 miles, and no amount of reinstalling the bearings with or without Loctite made any difference. I eventually bought a Wheels Mfg. BB30A screw together bottom bracket, which solved the problem for a while, but the creaking eventually returned. I currently have a BBInfinite bottom bracket shell waiting to be installed, if that does not fix the creaking I will probably try to sell the frameset on eBay for peanuts.
The first HongFu frameset I built up was the FM296 which has a BB30 shell. I used press fit BB30 to 24mm adapters to use a Shimano crank and only had some groaning occur after a downtown crit, but that was remedied by pulling the crank and putting a bearing press back on the bearing shell things. I eventually pulled those out and installed a Wheels Mfg screw together BB30 to GXP adapter, and that has been creak and groan free for about 4,000 miles and counting. The FM169 and TM6 both had screw together Wheels Mfg BB86 to GXP bottom brackets installed from the get go, and those have both been quiet.
These are just my experiences so trying to tease out universal truths from a sample size of four is impossible, but I have heard plenty of other noisy Cannondales on the road so I do believe that somewhere along the line from design to production someone got lazy and sloppy with their BB shell tolerances. Maybe it was the design engineers, maybe it was the project manager, who knows.
