Leviton was my least favorite when redoing our apartment approx. 18 years ago.
I purchased a box of Hubbell 8200 and 8300 outlets (like new pulls) and used some of the 8200's for regular outlets.
I also used some Arrow-Hart, Eagle and P&S outlets left over from HiFi experimentation.
All the above had a much stronger grip than the Leviton's I tried, plus I was replacing old Levitons that were worn/loose.
