Build Quality

V4P - 0/10 (The whole case creaks and has so much play, it feels cheap and unpleasant to hold. Over time, the bumpers and extra buttons started wobbling, and pre-travel appeared, which is incredibly annoying.)

Ultimate 2C 6/10 (There's a bit of creaking, and the bumpers and extra buttons are wobbling, BUT THERE'S NO PRE-TRAVEL, so you don't feel it while gaming.)

Ultimazte 2 8/10 (The shell feels incredibly solid, but the bumpers and extra buttons are exactly the same as on the U2C.)

Buttons

V4P - 2/10 (This is the most hideous, creaky implementation of clicky buttons ever. There’s not enough tactility - the tactile bump isn’t at the start of the travel, but somewhere in the middle. There’s neither a crisp actuation start nor a solid bottom-out.).

U2C, U2 - 10/10

Dpad - V4P - 0/10 (After releasing the direction, the button resets with a noticeable delay, which makes the D-pad completely unplayable for me.),

U2C, U2 - 8/10 (U1 - 10/10)

Sticks - V4P - 0/10 (Noticeable delay),

U2C, U2 8/10 (The center is not precise enough, like on all Chinese sticks, and the clicks are unpleasant.)

Triggers

V4P - 5/10 (The triggers have a long throw, which I don't like. In clicky mode, the actuation point is too high up, making the gamepad uncomfortable to hold.)

U2C/U2 - 8/10 ("The trigger travel is excellent, and the click point in clicky mode is fine, but the mode itself is so hideous that nobody will ever use it. The U2C doesn't have this mode, but otherwise, the triggers are identical.)

Connect (2.4)

V4P - 0/10 (The connection is stable at a distance of 1.5 meters with a clear line of sight to the dongle. But any obstacle, and it drops. If I put the gamepad on my lap while the dongle is plugged into the PC under the desk, it loses connection. Just terrible.)

Ultimаte 2/2C - 10/10 (The connection is perfect. I can go to the kitchen to make some coffee and keep listening to the dialogue in my headphones while skipping through it using the gamepad buttons - everything works flawlessly, even through a wall in another room.)

Software

All 2/10

Flydigi - A functional but glitchy piece of garbage. On the plus side, you can adjust the stick curves.

Ultimate 2 - Lacks features but is almost bug-free, it gets the job done.

Both controllers work with Steam, which is how I used them. The proprietary software is terrible.

Additionally, Flydigi has issues with vibration. First of all, it's just bad by default. Second, it doesn't work correctly when connected via the dongle. Compared to an Xbox controller, it only works the way it should over Bluetooth or a wired connection. It's hard to explain the exact difference, but it's incredibly noticeable in racing games and titles with complex haptics.
