General impressions: beta 5 seems to run much smoother for me than beta 4 did, and with fewer obvious quirks (random performance blips, tap-to-wake delays, apps not responding for a few seconds after launch, etc) — in the immediate post-upgrade timeframe, at least.
That said, a number of the issues I saw with beta 4 and earlier didn't manifest until the devices had been running for some time, so time will tell if any of them come back.
