It really depends on how
you like your car set up and what suits your driving style best tbh
In general, setting the front to hard can induce a little understeer and depending on bar size can also make the car feel a little skittish imo, however i found it does give the car a more planted feel on very high speed corners (although above speeds you wouldnt see on the road that often..)
I run mine (H&R 26/22mm) on Front soft and Rear hard as i prefer the way the car feels and find it suits my driving style much more, it gives the car a much more 'playful' feel and the nose is much more eager to turn in and the hard rear bar allows you to promote a little oversteer, this makes it possible to back the car into corners a little which is handy on track etc, more importantly it's fun!
This setup, for me at least, seems to work and feels much less skittish and far more planted on a bumpy wet road than hard/hard, although this is at the expense of a little less composure on very very high speed corners as the car wants to wag it's tail as it were, you also may find a little more steering kick back compared to hard/hard when near the limit but again i find it adds to the fun,
I will add that soft/rear is noticeably more comfortable for daily driving though but that could be different for your car / setup...
There's no right or wrong setup though and it's purely down to what 'feels' best for you, relatively easy to change so maybe have a play around to see what you prefer
