Of those options, I’d just stick with what you have, but I think you can do much better for an upgrade with your budget TBH.
Aero is going to be faster almost all the time. That’s why he asked about climbing speed. If 80% of your riding is at 10+mph, aero will be faster for all of that time. You can get Roval CL50 aero wheels (for example) at 1515g for not much more than DuraAce. There are other aero rims out there with 40mm and less cross sections where crosswinds won’t bother you as much, but some aero rim profile will be faster almost all the time, and many aero rims are close to the weight of the dura ace set you’re looking at but will be faster in all conditions.
