I have just lost my bahco slip joint grips on a job last week, and i am absolutely gutted. Had them for nearly 3 years and saved me quite a few times. However they are quite pricey.
My merchants have a set of 3 Rothenbergers which look similar to the pliers I have (no idea what make). Decisions, decisions ... all for a tool!! But then, it's an extension of my hands. (Shame those hands are joined to my "brain".)
Facom adjustable 181.25cpe are the dogs danglies. Had my pair for years. Ergo design and I like the push button quick release adjuster. Better than the rotten burger or Knipex
