There are definitely differences between the opponents, so adapting your play seems to be a smart move.

Going from $22 -> $33 tournaments, I would expect in general:

Your pushes will get called less.
Your opponents pushing range will increase.
The meaning of odd bets may change (like raising 75% of one's stack on a steal).
table VP$IP may go down.
Awareness of the importance of bubble and HU play will increase.
There may be 1-2 additional "good" players at a given table.


There are other changes too, these are all that come to mind. Each of those items above has several implications towards how you should change your play.
