Rwwear - I use both. For most new, good quality CDs they rarely show rip errors. J River will rip them fine. It gives a report that tells you if it had to retry any reads. If there are no errors, I just use that. dBpoweramp is better at reading damaged disks and it adds the option to have your rip checked against a database of rips of the same disk by others (AccurateRIP). I find the convenience of using J River for both ripping and playback to be worth it. Using dBpoweramp is easy, but it does mean you have to import the files into J River Also, sometimes on some classical CDs the tagging can get a little complicated. When ripped with J River, the tags are clean and consistent in the library. If you want the absolute best rip with the best checking, use dBpoweramp. If you are OK with an occassional issue, you can use J River for most cases and dBpoweramp when needed.
