GAME CONTROLLER
When I play video games, sometimes I use a gamepad and sometimes I use a keyboard and mouse. A gamepad can be held directly in the hands without the need for a table. Keyboards and mice can perform many complex and precise operations. They each have their own convenience.
其中A gamepad can be held...能不能用复数Gamepads？会不会引起误解？
末句They each have...convenience.能不能改为Each of them has its own convenience?
在该语境下哪一句更好，为什么？
