As others said, depends on the goal. First trigger upgrade I did was a volquartsen which was 1000 times better than stock. Then I replaced that with a Kidd. Traded the Volquartsen to a buddy.
Volquartsen is a really good trigger. I have a Volquartsen complete gun and it has been very reliable and accurate, A friend recently bought a drop in trigger and is very pleased with his purchase.
I run Kidd triggers in my three (so far) competition 10/22s. It is hard to imagine a better solution for shooting fast and accurate. I've shot VQ TG2000s, and while I'd hardly call them a poor choice, Kidd has eclipsed them.
That said, a BX trigger or a Brimstone trigger job will net you some pretty substantial gains at a lesser cost. If it's just a bench plinker, that may be enough.
I bought a 10/22 for a couple of hundred bucks from Walmart several years back. I found the idea of spending the cost of the gun on fixing the trigger offensive.
I decided to rework the trigger myself. I decided the main problem with the trigger was the drag of the reset detent. I figured that if I could remove that, the trigger would be a lot better. I disassembled the trigger, removed the detent and installed a modified reset spring I hacked from an AR trigger group. At first it didn't have enough umph to reset the trigger, but with some rework I got it working.
I now have a pretty good trigger on my 10/22 it's very light at about 2 lbs and the break is pretty clean and NO detent.
