The Asus DSL-AC88U has one of the most recent broadcom VDSL chipsets, it even supports G.fast. I have no experience of using it, but it seems to be getting a good reputation online.
One of the reasons I suggested they are getting better, I'd still not buy an AIO given the choice and if I did, then based on the issues mentioned previously it wouldn't be an Asus. You don't take top end money for a product, acknowledge the issue then when you discover you can't fix it, just ignore them.
My personal weapons of choice are as follows:
Modem: HG612 (in fairness the ECI is equally good for most situations).
Router: AC56U + Merlin - same CPU/RAM as AC68U, just cheaper and slightly inferior wifi, Merlin adds quite a bit of functionality and multiple fixes that Asus often don't or ignore.
AP: Unifi AP, better coverage than any router I've tested, rock solid and ample throughput for loads of clients/great admin & management features.
The only slight negative I've found is the HG612 sync is fractionally slower than the newer chipsets, but that's such a small a difference, it's not worth the cost/time to try and fix. I suppose others may prefer an AIO such as the OP, Draytek are decent and support seemingly lasts forever, Billion are decent and Zyxel get a lot of love elsewhere for consumer kit, the TP Link stuff is also surprisingly good for the money.
As the OP hasn't been more specific about what he needs, it's a bit vague. Pointless spec'ing him a product that isn't compatible with Sky if that's his chosen ISP, or with dodgy QoS if he has real issues with hogging in a shared student house (time of year).
