I prefer pocket pairs. High-card value and absolute hand strength become more valuable when shortstacked. Playability, suitedness, and connectivity become more valuable when deepstacked. Because you have more implied odds, the value of hands that can draw to something nutted is increased. When deep, however, high equity, low playability and frequently dominated hands become less valued. Small pocket pairs, in particular, require larger stacks to play, especially when setmining.
The only time this rule does not apply is when you are extremely shortstacked and can open-shove and assure a showdown. Because they rely on implied odds to draw, small suited connectors do better deepstacked.
