Ja, EFS is an Australian brand similar in price and performance to OME. They do various setups for the vehicle, with 3 different shocks, and a variety of different springs depending on the load rating increase you want.
I opted for an intermediate shock and a 150kg rear spring, and a 75kg front spring. I got a lift of 40mm both ends with this.
In terms of handling, the pajero rolls much less in the corners, and seems more planted on the road. In terms of comfort, it takes gravel roads and potholes much better. Its obviously a harder ride given the extra kg load rating, but its somehow more comfortable.
Well worth looking into if you want an alternative to OME, plus EFS has a much longer warranty.
