If you start from about 150 bbstats and 9-10 Enthusiasm, crunching and playing home will get you 2-5 bbstats less than TIEing and playing on the road.
If the options are normal+HCA vs TIE+no HCA, then normalling+HCA is the superior choice. However, the difference between TIEing and normalling should be around 4-5 extra bbstats in defending and rebounding (assuming a 150 total), which means you should normal instead of TIE only if the game is close and you want to make sure you'll win it even if the opponent normals as well or guesses GDP right.
