What's also useful is to look at your MyLog to see what aircraft you see most often. I'm currently using this SQL to decide what additional 3D models to create:
SELECT DISTINCT
Aircraft.AircraftTypeSmall,
COUNT(Aircraft.ModeS) AS Counter
FROM
Aircraft
WHERE
(Aircraft.ADSB = "Y")
GROUP BY
Aircraft.AircraftTypeSmall
ORDER BY
Counter DESC
Gives this top 20 of ADS/B aircraft:

B763 275
