For my front V I use avid RW2 pads, they are very nice, long lasting, lots of bite and modulation also. They are also cartridge pads which is a plus.
For my rear magura I use plazmatic CRM pads available from EZTrials for £16. OK modulation but I prefer on/off style brakes myself anyway. Lots of hold, no slide at all if rim is clean.
