I really like Usertesting and have been a tester since 2017. I've seen good changes and not so good. For instance, having a limited profile and that profile does not get referenced it seems. Qualifying gets tedious when if the question was a profile statistic you wouldn't have to take the qualifier. Not a fan for the new update as the old system was much more pleasing to the eyes. Still the best for UX testers imo.
