No, GP5000 is still pretty much the best (fastest) daily road tyre. Vittoria Corsa Pros are on the same level but tan walls only I believe. Michelin Power Cups are also excellent but there was some consternation about the tread width being too narrow for wide wheels (over 21mm internally) so you could give them a try if you wheels are narrow. I have used them and they do ride better that a GP5000, were cheaper when I bought them too. Probably less aero being completely smooth.
30mm should be standard in the UK anyway, IMO. Rolls faster over rough roads and the bigger contact patch means more confidence in corners or in poor conditions.
It’s often cheaper to buy from BikeInn and the like, but it really depends if there’s any offers on. GP5000 were cheap in the UK before Christmas but they seem to have gone back up to almost RRP last time I checked (a couple of weeks ago).
