looks great, good balance between function and design yeah i like the led strip price a bit high though wonder if this better than logitech G303 daedalus i hope they not releasing with rubber coating, as it turn to sticky after a while

No. And no mouse will be until the 3366 sensor goes public. But it could be "better" for you, if the aesthetics or shape of the G303 is an issue for you.

Proper gaming mouse is like HOTAS Joystick, must allows you to keep left hand on WASD, SHIFT, SPACE keys while performing most basic FPS functions (shoot, ADS, throw grenade, melee attack, crouch, prone, draw side gun, ...) this requires more than 5 buttons. In my opinion, in order to earn "gaming mouse" title it must have at least same amount of action buttons as a standard gaming controller which is 14 (A, B, C, D, LS, RS, LT, RT, LB, RB, D-PAD Up, D-PAD Right, D-PAD Down, D-PAD Left). Logitech G700 is a gaming mouse, QPAD DX-20 is not. "Ambidextrous" feature is a lie, because there are no buttons on the right side. 69€ for wired mouse with basic features is unreasonable when you can get wireless G700S king of gaming with tons of features for the same price.

Amount of buttons doesn't make a mouse a gaming mouse... besides that, you are comparing a wireless laser mouse with a wired optical mouse. Neither can you compare the price, the G700S costs 99.99€ at Logitech, I'm quite sure that the DX-20 will cost less than 69€ at larger local retailers, same as that the G700S costs less than Logitech's pricing. I wondered about ambidextrous too with it's missing mirrored buttons on the right side. Since when is an ambidextrous mouse with a nonemoddable shape ergonomic anyway? Personally I prefer the G502 when it comes to wired optical mice.

A gaming mouse mainly is a gaming mouse because of its performance. Also keyboard: https://www.youtube.com/watch?v=bexWuHmV32A them koreans playing starcraft :x Or some BF4 with a driverless Zowie mouse: https://youtu.be/57Rq_b8sagY?t=2m4s

Extra buttons is exactly what makes mouse a "gaming mouse", because extra buttons gives advantage over other players. Of course, higher DPI, faster pool rate, memory profiles and scripting makes mouse a "gaming mouse" too. For example, in Battlefield 3/4 I use this sequence very frequently when trying to resurrect friendly: With my left hand I am running ('SHIFT') forward ('W'), while strafing to the left ('A') and to the right ('D'). At the same time, with my right hand, I am selecting defibrillators ('G8'), holding them down to charge, resurrecting friendly, dropping medkit (Scroll-Left) taking out Main Gun ('G8') or Side Arm ('G6'), zooming ('R-Mouse') and shooting ('L-Mouse') at enemy in order to to provide cover for resurrected soldier, then I am immediately crouching ('G7') or proning ('G4') into cover myself. With G700 I can do it in a flash with ease, while constantly moving at the same time, because G700 is a real gaming mouse. QPAD DX-20 is not a gaming mouse. QPAD DX-20 will force you to use keyboard which means that your in game character will stop moving and it makes you easier target for the enemy. As I've said before, proper gaming mouse, like HOTAS (Hands On Throttle-And-Stick) Joystick, allows left hand to be dedicated for movement. Mouse with 14 and more buttons can be called HOKAM (Hands On Keyboard-And-Mouse) 🙂.

Sensor performance, shape, and software (or intended lack of), among other things, are what make a mouse a gaming mouse. Look at the Zowie range. Driverless, standard shapes, and few extra buttons, but are the favorite among many gamers, pro and casual. I own a Zowie FK1 and I wouldn't trade it for anything honestly, it's awesome. Extra buttons are for those who want extra buttons. I would avoid the MMORPG-oriented mice like the Razer Naga Hex for instance, but in your definition it would be the most "gaming" out of mice. Higher DPI is mostly a marketing gimmick (12000 DPI), and all gaming mice have a 1000Hz polling rate so that's a non-issue as well.

Metabans =/= a true ban. Just a server tool for badmins who can't take a loss. Either way, the idea that you need a gazillion dpi and over 9000 buttons to play well is moot. Once people realize that, we'll start getting ACTUAL better mice, but atm inflated numbers sell to much for the average consumer. The 3320 in this mouse should be more responsive then the 3310 sensor, but it'll come at a cost, reduced malfunction speed (meaning the mouse will most likely crap out on you when you move it faster then ~3.25 meters/second). The 3310 in comparison, does well over 5 m/s. The 3366, which is currently a Logitech exclusive (these are usually timed though, eventually a public variant will show up other brands can use) through an agreement between them and Pixart. However the 3366 offers the best of both worlds, best responsiveness combined with a very high malfunction speed. A "good weapon" as you like to call it should be good (AT THE VERY LEAST) at both reliability and accuracy. There's alot of mice out there that actually do not succeed at this, but to many people look over it because they're blinded by 3000 buttons and disco lights. If you look at the "pro's" on LAN and what they use, the things that come back the most will be: Lightweight, Simplicity and the 2 arguments I mentioned above, reliability and accuracy.
