However, just because someone LACKS feats, doesn't mean that they automatically lose. It just means the battle in inconclusive. So far, we haven't seen Sentry UNABLE to do anything that Superman is ABLE to do. Give it some more time, and we'll have a firmer basis of Sentry's power, and we'll be able to accurately gauge this fight.
Till then? The answer is neither Superman due to showings, Sentry due to speculation, or a draw due to the lack of information.
Rather, it is entirely inconclusive, due to the lack of information. Bump this topic in a year, and it'll be on.

Finally, somebody who thinks.
