Consultng tiers:
Accenture is not a tier-2 mgmt conslt firm. Don't get me wrong, its a nice place to work. Most people are genuinely good & smart. Also, if your interested in tech consulting, I think Accenture is probably one of the best places to be. Its the goldman sachs of that world.

Also, there is more money in tech consulting than pure strategy work. At least, when you look at the volume of work handed out..

Frankly speaking, can't really compare MBB's to Accenture. They're just so different.

Tier 1 - Mckinsey, Bain, BCG (MBB)
Tier 2 - At Kearney, OW, LEK (in some markets, people would argue for Monitor-Deloitte, STrategy& )
Tier 3 - Big 4, Accenture, etc.. (As you notice, tier-3 firms don't do just plain consulting work, but a load of other stuff).
