Enphase has just released the new S230 and S280 microinverters. These new inverters provide improved efficiency and power factor control between 0.7 leading to 0.7 lagging.
FWIW, Enphase does have a document which contrasts the M215, M215IG and the M250.
Edit August 18, 2016: Added M19072IG column to the table (Part No. M190-72-2LL-S22-IG)
Edit August 29, 2017: Replaced S230 column with M250-72 column.
For reference, here is a photograph showing the original M190 next to the M215IG:
