I also recently bought a new G23 and am not unhappy at all with the stock sights. My G22 does have Glock night sights but for most of my shooting the standard ones on the new G23 have been just fine. I'm in no hurry to make any changes at this time. Since you sound happy you might just want to stay put until something comes along that you like enough to make the change.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
