The last statement was a very common view at the start of XY but as it turns out it actually isn't true that LO Blaziken is strictly better. The only time regular Blaziken is strictly better than Mega is in Doubles where Blaziken isn't a strong enough contender for the Mega slot. In Ubers you basically only see the Mega (if at all these days) and Mega Blaziken is one of the big three Megas in Battle Spot even now with Kangaskhan and Gengar. The thing about Mega Blaziken is that it can afford to run Adamant, whereas regular is too slow to give up the Speed so it needs Jolly or Naive, which in turn makes it slightly weaker than Mega Blaziken on top of having more recoil and a lower Speed tier.The same for Mega Blaziken. Speed Boost just makes him insanely amazing, plus with the stat boosts it gets... glorious! Too bad regular HA Blaziken holding Life Orb is actually better.
