I am about to have a gas combi system installed. With 28 KW, it will deliver hot flow of 11.5 litres/min, with a 35 degree temp rise.
The pressure of the hot water needs to be no more than 3.5 bar when a flow of hot water of 5 litres/min is running. If it is more, then a pressure reducer needs to be fitted.
It is expected to give a much more satisfactory shower, than any electric unit.
The only better shower I can envisage would take pumped water from a pressurised stainless steel hot indirect cylinder, and cold from a large loft header-tank, and feed the flow thro' a "pressurised system" blender shower, such as the Combiforce or Combiflow units with pressure or temperature stabilation.
