I have the WRT ac1900 linksys on my gigabit internet and it's performed better than all of the ac3200 models I've tried including the asus, dlink, netgear r7500(2350). They are all pretty similar wired(~930 down), but upstairs in my house my imac hits about 550 down using the wrt. It got about 375 on the asus and low 300's on the others. I can't find any reason to replace it even with all the claims of cut through technology or acceleration on those other models.
