There are many different pads and to be honest, it is purely down to personal preference.
I used the Sonus SFX pads for years, found them to be superb and last a long time.
However, recently I changed to Lakeland County pads. These cut much quick with the Menz products, however, they are buggered after about two/three cars max!!! Pricey too!
I would stick with the Sonus products.
