I like ICW, Alliance, Strategic Improvement, EAW-RE/ORAW, RAW, Yoden, and Battlefront Commander (not in order). EAW-RE/ORAW for the graphics. ICW for the Eras, art style, perma-death (for heroes since AI spams them without it) and balancing. RAW and Battlefront Commander for good graphics and fun game-play. Alliance and Strategic Improvement for many units (plus filters and unit upgrades), large and varied GCs covering different arcs(?) in the EU, better garrisons (more structures can hold troops-SI99.7; Alliance has turret bunkers and super bunkers for vehicles), and better land battles in terms of defenses and defender structure spawns (SI99.7- planetary shield, vehicle depots/air bases/fortresses, Laser Tower which I turned into a buildable defense like the turbolaser towers; Alliance - Missile towers, armed walls, base turrets, and secondary command centers that also function as extra power generators). Yoden is fun to play (and unbalanced) with the defenses, easter eggs, large maps, and having space ships in land battles.
