To the best of my knowledge, there is no significant difference in seal issues between the two systems. The HWH slides are hydraulic while the Valid slides are electric operated.
The electric slides have the advantages of 1) no fluid leaks, 2) no long hoses to rot out, 3) less friction on Valid's ball bearing sliding surfaces, 4) no pistons to reseal and 5) separate motors for each slide so if a motor goes wonky it only affects one slide rather than having a pump goes out resulting in all slides becoming stationery.
Not sure what the disadvantages of the electric slides are unless you have very low batteries but that likely affects the HWH system controller also.
I am certain that some of those who have had both systems will jump in.
