My AC15 clone build will only be the Tremolo channel with two different gain inputs as that channel uses only 12AX7's of which I have plenty.
In the past I found tag strips pretty easy and very flexible. A bit more planning and earlier commitment is needed with any form of turret board layout. On my tag strip 50W 2204 build I got the circuit and built it from input to output in that order by adding tag strips and components as required. The AC15 clone has a generic turret board so will need much more early planning and adjustments to component placement as I build it. Turret board pretty well defines where your connections are right from the start but the result looks neater and is much easier to repair and service. At the moment my biggest headaches with the AC15 clone turret board planning is wire lengths minimisation and then separation of HT and the earth points, and there are a lot of earth points...
