IniBuilds’ LEIB is great but is showing its age a little now. Superb interior but devoid of passengers. Slightly unrealistic runway slope at the 06 end but runway markings are spot on. Sim-Wings (published by Aerosoft) also do a version which has a partial interior and static people. It also has the proper Spanish-style airfield lighting and more accurate terraforming. Judging by reviews, people are happy with whichever one they choose. I went with Ini’s and like it.
There are also two versions of LEPA, both quite old. Just Flight’s is definitely better than JustSim’s, although neither has been updated in quite some time. It’s actually developed by a group of Mallorcans called JSPCO, marketed by JF. Rumour has it that MK are doing LEPA so might be worth hanging on as theirs would definitely be better than both current offerings.
LEMH is only available from Sim-Wings/Aerosoft. I’ve no experience with it but their stuff is normally pretty solid. Not the most detailed out there but certainly the higher end of average.
