My mistake! Been on holiday and forgot time still runs at home!
Just going to add my 2p as someone who has ridden both rather alot. Llandegla is horrible. Nothing flows, its bumpy and wide and im sure they throw down rocks onto the trail surface to make it more like mountain biking.
Penmachno isnt a brilliantly made trail. Its more cut into the hillside, so it does become a bit of a stream when its mega wet. Loop 1 is normally fine with the exception of a couple of bits. It helps if you know the trail in order to get the best from it. If you dont, i think poor line choice will take away from the flow of it all. But it is fantastic and easily my favourite purpose built trail.
