Well let's compare the event's going on right now.
ASIA: D-Day Challenge (Gives exp boost and M10 Siroco), [SPECIAL] Dragon Boat Festival (gives EXP and Emblem, winning team reward unknown), [SPECIAL] On Track... EBR 105 (discounted specific tech line), [SPECIAL] 31st May Tank Mastery and [SPECIAL] Onwards to June (both gives exp boost).
NA: Play Your Tanks Right (gives Exp, Kits and Equips), Tank Reward Returns (gives Kits, Reserves, Garage Slots, Equips, Blueprints and not sure if you can get all but a Cromwell B, T34-85M and Strv M/42-57, will last whole June), Memorial Day Missions (Reserves, Kits and Garage) and D-Day Challenge (Gives exp boost and M10 Siroco)
EU: Special: Crew Boost (x2 exp for crews per battle), Top of the Tree: Get to the Object 268 (their version of On Track... (discounted specific tech line), D-Day Challenge (Gives exp boost and M10 Siroco) and a planed rewards for the whole month of June (gives Kits, Equips, discounts etc.)
Asia truly got more events, but the rewards are so-so. Exp multipliers are good but that won't help retain or attract players. EU got less EVENTS since it was requested or so, players can't handle what mission to prioritize. NA got more satisfying rewards for new and old, since the events they put out seems to qualify new players to some degree...
EDIT: IMHO, we might have more EVENTS (if you count SPECIALS truly as an event) but the rewards are less satisfying...
