Quality, effectiveness, longevity wise; then Tokyo Marui is the way to go.
There are a few good pistol companies that you can trust, WE is not on that list. Every WE pistol I've seen has been plagued by one issue or another, or several. WE guns often feel more realistic as Tokyo Marui guns are made of plastic, but the trade off is a train wreck waiting to happen.
This is just my opinion from personal experience. But I've also owned, used, a seen many in action from either side; and the results are always the same.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
