Quick comparisons between the two mice, Cyber Snipa is up first.
It has six buttons: right, left, scroll wheel, two thumbs and the last one is the ring finger button. The mouse has two different speeds, with a firm 2400 DPI or 1000 DPI. Color is a nice black with the logo on it as well as a clear strip that glows red or blue depending on what mode you're in. It also can be used with either your right or left hand.
G5 (Logitech), has four buttons, right, left, scroll wheel and one thumb button. It has three different speeds that are programmable (Default is 400, 800, 1200 DPI) You can adjust them all of the way up to 2000 DPI. It has a small window that lets you know what mode you're in. Wheel has the right and left tilt as well. Both use laser tracking, but the G5 lets you adjust the weights for those that tend to pick the mouse up during the game. It also is tilted a little to the right and is for right handers only.
It is nice to have the two extra buttons. I would have liked to have the G5 with at least the extra thumb button. The weight of the Cyber Snipa is on par with standard computer mice so there's nothing really different about that. Both use a laser for tracking and do a very good job on both mouse pads as well as my desk top. I think one of the big disadvantages the Cyber Snipa has is the locked in speeds for the mouse. Being able to adjust the tracking levels would be nice to get it set where it works the best for you
FPS: An first person shooter type of game is where the Cyber Snipa is designed for and it works really well. I was able to snipe guards and head crabs, plus everything else that was trying to kill me off in Half Life 2. Quake 4 during death matches I spent more time in the higher settings for easy hall turning ability. In single player mode I did switch back and forth a lot.
Real time strategy: I had to turn it down and use the lowest setting since mouse movement dictates how far away you want to scroll on the map. As I know this mouse was not made for this type of games. I show why I would like to be able to adjust the DPI setting with out making the mouse really slow in every other program as well.
Real Life computing (Non-games): the 1000 dpi mode works fine for this, the speed might be a little fast as Flexiglow said some people turn it down usually. It was close enough to my normal day to day level so it only took a little bit to get use to. I wished the buttons were mapable to anything and not a fixed list, for example, Shift-Ctrl-L for auto adjustments in Photoshop.
Overall the mouse is nice for FPS and is fine with everyday work, I did tend to have some problems with Atari's Act of War: High Treason with detail control. The mouse pad was not too small or large for me, as it was close to the same size of a pad that I have been using for a couple of years now. I was able to keep the mouse on the pad at all times without having to pick it up. The mouse curves to your hand and is adjustable for either right or left handed usage. I do feel that both of these items are a great combo deal.
