I can't say honestly. The stock bridgestones re97as-02's were on the car for less than 500 miles. They were utter crap in every imaginable way.
In terms of speedo accuracy, they too were off by about 1 mph at 60 per gps. That is, speedo showed 60, gps showed 59mph. I'm getting roughly the same error with the as4's in the size shown. When tire shopping, i didn't directly compare sizes in terms of advertised size, rather I looked at revs/mile. There is too much variance in revs/mi with tires even of the same advertised size.
I don't recall the numbers exactly, but the difference was less than 10 revs/mile iirc.
Some people like the DWS06+ too, supposedly they're very close to the as4's but slightly cheaper. I've been using michelin tires for nearly 2 decades, and across multiple vehicle types (see left), so a bit of brand loyalty and positive experience, at least with their performance or semi-performance tires.
In terms of comfort, the as4's are not extremely harsh, but you do get lots of feedback.
We'll see what's available when the next tire change comes around (few years), may try the dws's, may go with the as5 or as6.
