Am I being too picky with a recently acquired Tokina 17mm f/3.5 AT-X Pro AF lens?

I recently acquired a used, but minty Tokina 17mm f/3.5 AT-X Pro lens for Nikon. I picked up this lens from eBay hoping to replace my Sigma 15-30mm EX DG lens as my budget wide angle. Despite the Sigma's flaws of being bulky, having a bulbous front element and terrible purple sun flaring, where it makes up is the ultra wide 15mm FOV, bitingly sharp center sharpness (causes moire on the AA filtered D750) and I bought for under $200 USD!

I like all the external aspects of the Tokina due to being built-well, having a non-moving front element and it's the most compact AF rectilinear wide angle prime that takes filters. The good optical aspects of the lens is that it has minimal distortion, excellent flare control, nice colors and decent contrast. Though I find the sharpness is average at best on a more a recent 24mp D750 sensor. I've already AF adjusted the lens and usually stop down to f/4.5 to eek out a bit more sharpness. Does anyone have experience with this lens?

Is it possible I have a bad copy and should consider finding another lens or am I just expecting too much from an old lens? I own lots of old Nikon AI-S MF glass and despite being old designs, they all still perform well on my D750, so I know age can't be too much of a factor! The only other thing I can think of is switching to a body with a better screw drive motor (maybe a D3/D4/D5 series body). Thanks for any opinions!

A couple samples from the Tokina 17mm f/3.5 AT-X Pro AF lens + D750. Everything looks okay from regular viewing distances, but it doesn't have that extra bite you get from decently sharp lenses when viewing up-close:

I guess I wouldn't necessarily expect the Tokina to be "bittingly sharp." I had the Sigma 15-30 way back in the day and thought it was pretty sharp, at least in the center, so I wouldn't be shocked that the Tokina is not an improvement.
