Raven/Clipper/Astro is more forgiving and easier on the pilot. Doesn't your prospective/future employer have clear take on this? The only other reason for doing it in 44 could be the CFI sign-off coinciding with reaching the required 50/25/200+ hrs and not having to pay extra for checkride for the endorsement if you've done your ratings already.
