Accenture, Deloitte & IBM are considered Tier 2. The BMW, Mercedes, Audi if you will.
McKinsey, Bain, BCG are Tier 1. The Lamborghini, Ferrari, Aston Martin, etc.
Tier 2 do their darndest to get into Tier 1 but the nature of the work is very different and the chasm between tiers is hard to cross just like in the car industry. Source: I've done extensive work in both tiers.
In this case, the smaller companies are, if anything, slightly higher-end (more boutique).
I'm not actually sure the Tier 2 are trying to become Tier 1. It's like comparing Walmart to Tiffany & Co. They're very different business models, but upscale doesn't necessarily beat mass market.
My experience is the Tier 2 vendors you've listed are more tactical, and typically handle execution (outsourcing etc.).
Whereas MBB are more strategic, C-Suite, but the value-add may or may not be significantly different from the former.
What about EPAM Systems btw?
Edit: I was confused by this:

IBM cloud has nothing to do with AWS or any other provider. It is an autonomous provider just like AWS, Azure, Google, Alibaba, etc
Disclaimer: Close friend works there.
Jesus, get your facts straight before shooting such inaccuracies.
The most basic googling will show this is a lie.
Outside of mainframes, from my own experience, their Spectrum Scale/GPFS (parallel filesystem) is still the default buy in HPC. Not necc the _best_ choice, but still the one you wouldn't get fired for buying.
One of the other admins was investigating the Lustre filesystem when I left.
Plus I'm sure they do sell enterprise software at extortionate prices
Not sure how much success they're having with their other cloud offerings, tho.

Revenue Highlights 4Q19 Total Revenue $21.8B
Cloud & Cognitive Software $7.2B
Global Business Services $4.2B
Global Technology Services $6.9B
Systems $3.0B
So Watson is a portion of the "Cloud and Cognitive".
Further down, it shows just the Cloud part:
Cloud Revenue $6.8B
$7.2B-$6.8B=$0.4B
Not bad, but $400M in Watson "Cognitive" revenue isn't a notable portion of $21.8B.
You get better information from their annual report.
