Starting with a 3-dice baseline:

3 Dice, Focus + Target Lock: average 2.8 damage, with about a 1.1% chance of 1 or fewer damage, 16% chance of 2 damage, 83% chance of 3 damage.

4 Dice + Target Lock (that is, using Expose): average 3.0 damage, with a 5% chance of 1 or fewer damage, 21% chance of 2, 42% chance of 3, 32% chance of 4.

So you trade consistency (a nearly 10% higher chance to get 2 or fewer damage) for a possible upside (32% chance to get in 4 hits), so 4 dice single mod are probably a bit better than 3 dice double mod. The cost, though, is huge. The cost isn't just the reduced agility. It's the 4 points spent (maybe even 7 with Experimental Interface), and filling your Elite (and Modification) slots. On a Decimator, I'd personally rather have Predator or Veteran Instincts and Engine Upgrade, rather than Expose and Experimental Interface.
