I used a netgear before retiring it to a guest network access point. When used as a router, I had to restart it once a week or so, now maybe once a month. I've never "had" to restart my Apple routers or Time capsules except an older extreme I hung a number of USB drives off of. Sometimes I had to restart to get all the drives recognized. The current generation extreme doesn't seem to have this issue, although I haven't tried it.
I don't see any downside to the extreme for home use. It just works.
