Can depend on your drivestyle liking, if also for racing, such as you want to bias under or oversteer and can be done as to the diameter of the sway bars, are they hollow or solid and also if using GM stock end links or wanting adjustable ones
Correct Oversteer Adjustments Correct Understeer
Stiffen (Thicken) Front Sway Bar Soften (Thinner)
Soften (Thinner) Rear Sway Bar Stiffen (Thicker)
Makes a different if you want softer on front, stiffer on rears, the other way around or both same diameter
GM Parts Performance sells sway bars, so they have been tested depending on Corvette model years
where buying from 3rd party vendors, you better be sure they list what they are made of, if hollow or solid
Adjustable end links allow adjusting to bias how the car tracks on roads
Example on my C5

Going with the wrong ones, you could pay the price as example
For Open Road Racing a guy owning a 1999 C5 FRC (Billybob) had years of drag racing and never did ORRs
He was used to wanting just going in a straight line on dragstrip so he selected rear stiff sway bars
I warned him what he had chosen was going to prevent C5 FRC making high speed right and left turns or S-turns
ORRs using normal public roads in mountains lots off non cambered blind turns
At around 160 MPH going into a turn, the C5 had bad understeer due to too stiff swaybars,
C5 never made it through the turn, and it went off the road into boulders, weeds, etc and C5 flipped multi times
and he ended up in a hospital for several weeks
So think about the type and spring strength weight you want and suggest going with the adjustable end links to dial in how
