Modifying the Doctor lamp board is pretty easy. Only takes around 20-30 minutes.

Short summary
You remove the molex connectors and stand-offs and lamp sockets. Buy some 555 LED's and unfold the wires from the plastic holder and remove the LED with wiring from the holders. Bend the wires into an S curve shape so that the LED are wires and now a horizontal disc and solder them into the location of where the lamp sockets were. Now make a 6-12" long wiring harness soldered onto the board where the molex connector was. Attach a new Molex socket on the end of the wiring and attach that to the factory connector using a Z-connector. Mount board flat against the speaker panel with no standoffs. LCD will now fit directly over the doctors lamp board.

The tutorial shows re-using the removed male molex pin connector. I prefer to use a female molex connector along with a Z-connector to avoid having to use all the shrink tubing or tape to cover up the exposed terminals.

For me it comes down to this;

LED version is brighter, a few bucks cheaper and easier to install.
LCD allows more animation variations with the connected/interlaced dots.
Not sure which one has more power draw on the 12V and 5V circuits, but I imagine it's the LED.

LED is usually preferable unless the game has great cartoon like animations, like AC/DC, Stern Star Trek and Doctor Who. So it's a toss up in this case
