Soma everwears are my skid favorite, I've managed to commute brakeless with skidding involved, because I live in the hilly part of town, on my last one daily for a year and half. The only thing I have against them is how they lose cornering ability as they wear down and tire contact surface wears flat. It's expected for all tires with skidding but you have to live with the fact longer due to the sheer amount of material on the tire. With skidding, thread material/ life is everything.
I've never tried a thickslick and I don't plan to unless I get one for free, the lettering is a bit too corny/ overly bold for me.
