I've gone with Bon Chovy four times and Pacific Angler once.
We request Jason A. at Bon Chovy. We've gone with him three times and he works hard and has a great attitude. Catching fish is never guaranteed but he'll work hard to get one on the line. That said, we've always come back with at least one salmon even on the winter chinook charters which can be slow fishing.
Went with Pac Angler once when Jason wasn't available. Got a guide named Jason then too! He was also great. Both he and the company were professional and I'd go with them again if I can't get the Jason at Bon Chovy.
I've done a number of other charters over the years and BC and PA both run good boats and fishing gear. Those are the only two charter companies I've used but my dad and I had really good experiences with both outfits and we'll stick with them in future

On a side note, you may want to think about doing a longer charter this time of year because sometimes it's worth heading over towards Gabriola for fish. It adds some travel time and isn't feasible on a five hour trip. Check with the company you decide on to see if the fishing is good enough to warrant making the trek over (it's about an hour each way).
