I've bought most of the commercially available calibrators, and settled on the Calibrite (formerly i1) Display Pro.
The Spyder uses lower-quality lenses, and calibration isn't as precise as the i1, so I returned it.
The Studio is good if you want to make paper profiles. I did that, but I found that my paper, Canson Baryta, already had a better profile than what I could come up with on the i1 Studio.
The Studio also took much longer to calibrate the screen. So I returned that, too.
The ColorMunki stopped working when I bought an M1 Mac, so I sold that.
I've settled on the BenQ SW270C monitor, which has built-in calibration software that will run all of these devices.
So all I had to do is calibrate my monitor, and use the Canson profile.
The main adjustment I made to the monitor calibration was to lower the illumination because I found my prints were consistently dark, which meant my monitor was too bright.
So before calibrating, I entered a brightness value of 60 cd/m2, about half the standard value, and the monitor software made it happen.
