If you want the very best and can afford it, go with the Wilson. Sinclair makes a few goodies for the Wilson if you feel the need for those, but that trimmer set the standard bar extremely high back in the day.
If you just want an excellent trimmer, then the Hornady, Forester and others will do what needs done.
