Logitech g303 vs. g402

Solution
G303 heavily depends on your form of grip and if you like it's shape and sensor. G303 is a claw and fingertip grip, more favoring to those of fingertip than claw. Taken into consideration it's size dimensions are Height: 115 mm (4.53 in), Width: 65 mm (2.56 in), Depth: 37 mm (1.46 in), Weight: 127 g, mouse plus cable (4.48 oz), Weight: 87 grams, mouse only (3.07 oz), so it's an overall light mouse and for small hands.

The sensor is a currently proprietary PixArt PMW3366, which has been known (and even tested by myself) to be extremely responsive with fast swipes and even low/high sensitivity swipes do not cause the mouse to malfunction and can have Logitech Profiles saved onto it's onboard memory.

The build quality is good and...

The build quality is good and the switches use a tension spring system that is extremely responsive to finger pressure, DPI ranges of sensitivity is exceptional (up to 12000 pixels per inch!) but I found jittering to be a problem above 3000-6000-12000 dpi ranges, which is more than enough, a bit overkill in regards to other mouses. I personally have two levels of 200 and 400, 200 for very precise shots and 400 as my default. The price in the UK for one in PCWorld is around £40 - £50. I would recommend purchasing it for the sensor alone.

However, there has been a few reports that the sensor has a rattling issue but these reports are infrequent to make it a relevant concern.
