Well, it should have a top sensor. Basically, however, all manufacturers use the same. Large companies such as Logitech, Razer, Steelseries, Roccat, etc. modify their models via firmware in cooperation with Pixart. Basically, they are actually the same sensors. The budget mice of these companies also do their job excellently, but then they may not have the opportunity to change the lod, for example, or not so good basic values or smoothing etc. with higher DPI values. But a $30 mouse with a good budget sensor like a Pixart 3335 will do the job and I don't notice any difference to a Focus+ or 3389, OwlEye whatever. The only thing I notice and what bothers me personally is that with more than 3200 DPI and a sensor without the possibility of reducing the lift off distance, it becomes too shaky when I put the mouse back on the pad. Then a Focus+, TrueMove pro, 3370 etc. shines and makes sense if you like to play with max. DPI.
The mouse whose shape feels good to you is best. If the quality is OK and it has a good current sensor, everything is fine. Deathadder v2 is a great mouse by the way.
