Re: Perf board
I suspect there's an element of "horses for courses" when moving up from Veroboard.
The perf board with a ground plane (and ideally a power plane, especially for certain TTL families) will be good for logic, with a regular array of 0.1" DIL devices and decoupling caps, but the Manhattan construction over a ground plane, possible modular, has advantages for RF/Analogue, where you may have devices such as coils, filters, crystals, etc with leads not on 0.1" pitch, and you may need to add extra components such as stoppers or decoupling and specific parts of the layout.
On a related topic, you need to be careful of using sockets for some ICs, the extra impedance in the power and ground pins can be a killer.
I have some QRP meTube panels as well as some SIOC "expanders". I fancy having a go at a TRF, with a valve regenerative detector and an SOIC for the audio.
