Every GM I have owned (including my first car, a '76 Skylark) has been more reliable than the ONE POS Toyota I owned!
I've never owned a chevy but I've owned Jeeps and Fords and they were all more reliable than my one piece of crap Tacoma I owned. Owned that thing for not even 2 years and spent over $3000 just in maintenance on it. The vehicle I bought before it was an XJ and I spent maybe $600 in the couple years I owned that before the wife made me ditch it for something more "comfortable"
Now I just bought her an accord for her comfort and I'm back to using my Ford Ranger. It sat for 2 years in a shed, cost me just shy of a grand to get it running like a top. I don't even want to think about what that tacoma would cost if it sat for 2 years inside a shed.
