Well, the Hymotion kit seems like it might be cheaper when it comes out. The Hymotion Prius kit is around $10k for a 5kWh pack. They haven't released their 12kWh kit for the Escape yet, but since it is a 12kWh pack it is likely to be twice the price....so maybe $20k-$24k? Last I heard from Hymotion (in late Oct), the Escape kits were only being sold to fleets but they expected to begin sales to the public in about 3 months which would be around this time.....

I think the big difference between the two companies is that Hymotion leaves the factory battery intact and adds a supplementary battery, whereas Hybrids Plus seems to remove the factory battery and uses only the LiIon pack.
