Should you split 2s against a 7?
Split. The book hits two 2s against an 8 through ace and splits against the rest.
Why
Kept together, two 2s are only 4. One card takes 4 to 15 at most. Split, and each 2 starts a hand of its own.
Against a 7 the dealer goes over 21 26.2% of the time and ends on exactly 17 36.9%. Two hands starting on 2 do better against it than one 4.
When the answer changes
This one doesn't change. Every rule set the chart covers splits 2s against a 7: one, two, six or eight decks, the dealer hitting or standing on soft 17, with or without double after split and surrender.
The full basic strategy chart for six decks, dealer hits soft 17, with every other rule set a tap away.
