1. USN studies prove that a larger carrier is more cost-effective than smaller ones. i.e You get more bang for your buck with large supercarriers.
2. OTOH, large carriers and indeed the carrier group, represent a *substantial* cost investment. Which is putting your eggs into one basket, especially for an ICBM/DF21-D type (somewhat less so for a lucky shot/submarine/air attack).
3. Also, the thumb rule is ~3 carriers (1 in refit, 1 working up) for every one in operational use. So having one or two large supercarriers suffers from that availability aspect.
4. Smaller carriers have far less capable air wings; compromising on range/usuable payload and indeed coming down to either helicopter carriers or STOVL aircraft at some point. The only modern STOVL aircraft is the F-35, where India is clearly on the outside. (politically & economically).
Larger carriers allow for more effective AEW/ASW wings, and even fixed wing AWACS at some point.
At the lower end, one can even talk of "post carrier" amphibious assault ships, with part time helicopter/STOVL air wings.

The gripping hand (critical point) is to figure out what purpose the carriers are meant to serve. The USN has an answer, which doesn't necessarily apply to India. Sea control/power projection etc are part of it., but the USN is clearly heavily influenced by principles espoused by Alfred Thayer Mahan.
To confuse the issue, power projection and sustenance in a blue water/expeditionary scenario is very different from a near-shore/littoral scenario, and the risks and potential capabilities don't completely translate from one to the other.
I like this article (
http://www.usnwc.edu/getattachment/86e3 ... ea-Control) which talks about the purposes of an aircraft carrier as "eyes of the fleet", cavalry/ raid/hit and run/disruption, capital ship, nuclear strike and floating air platform, gepolitical chess piece and potentially mothership for assault.
The problem is that aircraft carriers are long term investments, and India has no clear doctrine. Plus since India's economic capabilities, political and military situation is also changing rapidly, (and technical capability a little less rapidly) it is difficult for India to come out with a clear doctrine and plan our fleet around it. (eg

Instead, we try to fudge/hedge our bets. Unfortunately, we have challenges in both long term thinking and in opportunistic purchase, due to limitations of our procurement process.
Clearly, aligning with the US can have substantial naval air benefits ranging from more effective large aircraft carriers (EMALS, possibly in large nuclear powered carrier), to small (F-35 base assault ships/small carriers); aligning with other western powers may help (UK, Italy, France-Mistral etc) or Russia (nuclear power,
shipbuilding).
The Indian Navy is well advised to keep its options open and create/build upon traditions and capabilities that we possess.
[An example of trade-offs, Large supercarriers are very vulnerable in green water near-shore (eg Karachi) scenarios to Pakistan's AIP/conventional submarines, but can be pitched somewhat against pakistan's land based air force), their presence in the Gulf or South China sea risks political imbroilement, of a sort we haven't had to decide so far.]
Ultimately, we are still growing and have not figured out who we are as a nation. The IN expression of that identity and it's translation in form of the number and size/capability of our aircraft carriers reflects that.
