I have the T/C and the x-bolt, never fired a vanguard. The TC is very accurate... 1" easy with most factory ammo I've tried, except 150 grain Federal Premium (.270 Win), and my best handloads shoot 0.5". The stock feels cheap, and owners manual claims stock removal is not user-level maintenance but I've never experienced a problem with it, to include the tacky panels peeling off. I sent it back for the first recall even though I had experienced no issues...had it back in two weeks or so...have not responded to the latest recall because I'm in the desert and don't come home till a bit later in the year. I bought it to have something to hunt with that wouldn't concern me when it gets scratched up, and found the accuracy to be an added plus (it beats out my M70, also in .270... But I got that one right before last season and didn't get much time for load development)
My x bolt is chambered in .243 Win and it looks nice (it's a medallion with the glossy stock). I will admit that even though I've had it several years I've not taken the time to find or load anything that it shoots well. Maybe I need to check the scope mounts, or some other troubleshooting...I've really just not put a lot of time into it. Maybe next spring I will get back on it...I should because it's a really nice rifle. It's heavier than the venture, thanks to the better stock. Plenty accurate for hunting tho.
Both my venture and x bolt have great triggers... Although the venture is the better of the two by a smidge. Don't have a pull gauge so I don't know the weight. T/c trigger is easily adjustable, don't think so for the x bolt (I just don't remember if it's user adjustable or not).
I've heard good things about the vanguard too.
