Non-electric or electric, and they are different products
This family splits cleanly in two, and the split decides your bathroom rather than your preference. Non-electric seats tee off the cistern supply and use line pressure; they need no socket, cost a fraction, and deliver water at whatever temperature the supply is. Electric seats heat the water and often the seat, and they need a socket within reach of the toilet — which most European bathrooms were never built with, and which is subject to the wiring rules for damp rooms in your country. That is a job for a qualified electrician, and this site says so rather than working around it. Beyond the split, the specifications are the seat ones — length, width and hinge hole spacing, exactly as on an ordinary seat — plus the water connection, usually a 3/8 or 1/2 inch tee at the angle valve. We compare power requirement, water supply connection, nozzle count and adjustment, seat length and width, hinge hole spacing, and whether water and seat are heated.
