I have purchased and own (in order) ProChrono, Shooting Chrony Alpha, SuperChrono and MagnetoSpeed.
I have shot the ProChrono and Shooting Chrony back to back and they differed anywhere from 5 to 70 fps. The ProChrono seemed to give the best readings of the optical chronies, but it varied quite a lot (up to ~ 100 fps) depending on light conditions.
Got the SuperChrono earlier this year and took it to a long range shoot get together in Townsend and set it up against an Oehler 35 and MagnetoSpeed
Here are the results of that...
I processed the raw data that Broz recorded to calculate actual MV for the Oehler and SuperChrono. I threw out the first shot on the first string since the bayo had come loose. I added 9 fps to the Oehler readings and 8 fps to the SuperChrono readings. Then I calculated the differences between the Oehler and Magneto and the Oehler and Super. Then I calculated the ES's for each string. I think the results were interesting.
ES' of the all the readings were fairly close, especially the last 3 strings.
The Super recorded lower readings than the Oehler with the 2 highest velocity strings. It recorded higher reading with the lower velocity strings.
The Magneto was the opposite of the above.
Both the Magneto and the Supper agreed more closely with the Oehler with the slower velocity strings with the Magneto being the closest.
The greatest Magneto/Oehler difference was 13 fps with many in the 1 fps category.

The SuperChrono was set up about 14' from the rifle muzzles which turns out was closer than recommended by the manufacturer. So, I got my own Magneto and did some more testing and set up the SuperChrono 20' and 25' from the muzzles of my rifles. Results were pretty much the same and more erratic than the Townsend shoot.
Here is a sample from a couple of work up strings with SC 20' from muzzle.
300 RUM, 230 Hybrids, RL33
..........MS......SC
97....2963....2969
98....2962....3001
99....3037....3090
100..3105....3136
101..3121....3208
102..3162....3198
103..3192....3221
300 RUM, CEB 180's, Retumbo
..........MS......SC
97....3376....3441
98....3401....3382
99....3472....3517
100..3506....3523
101..3548....3530...blew a primer on that load
Here is a 5 shot string from a 6-284 with 105 hybrids and 64 gr of RL33 (a very compressed load)
MS.......SC
3543...3536

I recorded several more same charge strings with the 6-284, 6.5 WSM and 300 RUM with basically the same results.
The SC was overall more erratic and based on findings from the Townsend shoot, the MS was more reliable in my estimation.
In reliability and accuracy, I would rate the SC in the same league as the cheaper off the shelf optical chronys. It's benefit is, light conditions don't affect it, it has a large reading window, can be used any distance down range and it's easier to set up.
The benefits of the MS are very reliable and accurate data and not affected by environmental conditions. When shooting more than one rifle, it's a bit of a PITA to change from one rifle to another, especially if you are alternating rifles to allow barrels to cool. The PITA factor is greater with muzzle brakes. Another draw back I found was the MS did significantly affect accuracy and POI. One example, shooting a 3 shot string from my 300 RUM @ 100 yds for velocity, followed by another 3 shot string without MS for accuracy, The string with MS showed a vertical group of 1.75", 1" left of POA. the group without the MS was 0.21" in size and 2.2" below and .5" left of POA. I had similar results with other loads and rifles. So bottom line for the MS is it gives accurate and reliable info but you can not do any reliable accuracy work with it attached to the muzzle.

I have the Shooting Chrony and the Magnetospeed. the magnetospeed is going to give you the most accurate readings because it doesnt use light it uses magnetic field and things like gas dont affect the reading... My one concern with magneto speed is the little computer display box seems a little cheesy but I havent heard of anyone having problems with it either so.. if it holds up magnetospeed is worth the extra$$
