I would think Summer tires could be used in SoCal winters but if you plan to head to snow country, summer tires are an absolute no go.
I use continental DWS all seasons and they do very well in regards to wet and dry. They are also very good in snow (when the tread depth is optimal). They have long life, comfort and very good dry traction for an all season. Steering response is good and feel is adequate, though not on par to summer tires, as to be expected.
I can't say too much more about others as I've not owned many cars, SUVs and trucks, mostly. I had a good experience with Michelin pilots on an Acura but can't remember the model.
I'm looking at nitto neo gens for my next tire as they seem to provide more grip but at a loss of tread wear. Want to extend my driving time on the new rims and then switch to a performance winter tire when the snow finally hits here in late December through February.
