These are my go to tire. Love the 4000s which just retired and have the new 5000s. The 4000s sidewalls has a tendency to blow after so many miles though. These 4 season have good flat protection, good roll and great grip. Rode 4000s and dura skin for years. These are all I ride now. I put on 10000 miles or more a year between commuting and weekend rides and good wheel sets, tires and saddle make all the difference.
I use Continental Gatorskins on my road bikes. These Continental Ride Tours are the answer to replace the (original?) tires on my recently purchased lightly used 30-year old vintage Trek 7000 which I bought as a neighborhood rider to keep at my daughter's house to ride with the grandkids. The price was right and the product description hits the mark. Eight thumbs up.
