I haven't done any research but my guess is: Stockfish?

Sounds like a good guess. Komodo/Doch should be a contender too.

Here is an attractive game it played in a blitz (5mins, ponder on, 3.6GHz) with a personality I have been working on:

Let's define TOP engine >= 2800 CEGT rating.

Stockfish for sure.

I know that you are joking but Ippolit is not a candidate because
Ippolit is not a top chess engine by definition:

TOP engine >= 2800 CEGT rating.

I realise you're just having a bit of fun, but any discussion in here about this engine will mean that the thread will be split and moved into the appropriate subforum.
