How do you play apothecary? Do you stick to a support role, or do you take a more "active" approach to your class. Do you prefer meele or ranged? Do you play prestige classes with your apothecary (Ravenwing/Wolfpriest/Sanguinary Priest)?
Personally I like to go Tyrannic War veteran apothecary, I feel like it helps make Apothecary a bit more dangerous in combat will retaining the ability to support my kill team with my medical skills/knowledge of Tyranids.
