I've been with AAISP since broadband was first rolled out back in 2000, and they have been pretty good.

They are not the cheapest so probably not so good for the average person who justs wants something cheap.

They have quite a lot which would appeal to more geeky types, such as a very good control panel which shows lots of things, like a graph of latency which runs 24/7/365 so you can monitor your connection quality.

They also give a block of real IP addresses so you don't need NAT, you configure your reverse IP, you can set interleaved/fastpath and you can configure stability options to optimise SNR margins, but this is all stuff that would be pretty much wasted on non-nerds!

Other good stuff is that there is no port 80 cache and no ports get blocked, so basically a "clean" connection wheras most big ISPs run a webcache. Again no big deal to the average surfer out there but all good stuff for techies!
