For my store, there were a LARGE number of bugs that were fixed in the upgrade between 5.2.6 and 5.2.10. I could not operated using 5.2.6 like I am with 5.2.10, I definitely would recommend going to 5.2.10 with the caveat that you make a copy of your store to another directory and do it there first, and that you make a backup of the database and especially the files. I did have a major crash from 5.2.6 to 5.2.7.

Tons of orders now in our 5.2.10 store, a few modules are screwed still but overall working quite well.
