I'm not familiar with the 3x9x32 scopes you mention, but I can offer some comparisons between the two brands.
I used a Vari-X II 3X9 on my '06 from 1973 through 1997. It worked well, never losing its zero from one year to the next, nor when accompanying me on involuntary, high speed descents down mountainsides.
For no particular reason other than "try something new", I put on a Simmons "44 mag", 3 or 3.5X10 (I forget, and I'm too lazy to go look.) I moved the Leupold to a bolt-action .223.
So far, all's well. The Simmons has held up while riding around rough jeep trails in my 4X4 without losing its zero. I've gotten tight groups at 100 yards; I took an antelope at around 100-125 yards; and I've gotten under MOA at 500 yards. I have no reason to complain.
The acid test is to shoot one shot at 100 yards on nine power; reduce to three power and shoot again. If the shots are within the usual group size for your rifle, you're in good shape.
All that said, I agree that the Leupold will serve a bit better at dawn and dusk, due to the better quality coatings. I'd also assume better repeatibility on the adjustments. (I rarely change the adjustments with range, in a hunting rifle. Once set, I leave it, so repeatibility is not an issue for me.)
Hope this BS helps,
