No.

LED display is easier to "power up", but uses much more current. An LCD
display with matching driver, assuming you "know how to connect it all", will
run on microamps (see wrist-watch, or most digital calipers that run five
years on one "aspirin-sized cell").

In bright lighting, the LCD is perhaps better. In a dark "corner of the
shop", nicely-made LED displays can be easier to read. BUT, even the most
efficient LED readouts hog current, SO are not candidates for battery-supply,
etc.

A matter of "whatcha gotta DO at the moment". Or, what "surplus leftover
parts" you happen to have on-hand!
