I know people who have changed from other grinders, just for the convenience of direct dosing into the Portafilter and the lack of mess, clumping and ritual.
IMO the answer to the OP question depends on your grinding style. So it may not be about which grinder model is better, but about which better fits your style. Here are a few examples based on the way I use the grinder.
For those of us who load the grinder with one dose at a time and empty completely between loads, the electronic minis are unsuitable. But the stainless housing used by the electronic models can be bought separately to replace the standard mini doser. (You will also need a plate to cover the opening left by removing the doser.) While relatively expensive, it's simple and effective in providing good grinds delivery to the portafilter with a good grinds distribution. And it is easy to clean the grinder throat and the inside of the funnel completely between loads. So it has the delivery effectiveness of the electronic models without the electronic timing and dosing features.
The collar requires a good amount of force to operate. It comes with a little handle that you can screw into the collar at whatever angle you deem best to get some leverage to make turning easier. I bought a second handle and with the two I can quickly and easily steer the collar to the desired setting. For me that's about 6 for espresso, about 7 for vacuum, and 8 for press. Quick and easy to move between types of brew and also between the slight point changes between regular and decaf shots.
Finally, it is easy to provide an external device for holding the portafilter at the correct position and height below the funnel. I removed the attached holder and use a platform made of two hockey pucks (Go Leafs!). I carved a notch in the top puck to allow for the portafilter spout to fit and for the entire portafilter to sit snugly and level under the funnel. This little tower sits on the grinds tray which can be pushed under to fill and then pulled away for leveling and tamping. Easy to adjust height with various coasters of different thicknesses, and also to allow for the use of small glass or stainless containers when grinding larger amounts for vacuum pot or large press.
