From what everyone says the accu-trigger is the real deal,never heard anyone say they didn't like it.......so I would say to get the one with the accu-trigger.
As far as the choice betwwen the 243 & 308........well this is my opinion.The 243 is definately capable of taken deer but you got to put the bullet where it belongs just as you would have to with the 308.But IMO you have a little more margin of error with the 308.
For varmits & coyotes tuff to beat the 243.I shoot a 243 and the reason I bought it was for a multi purpose gun,yotes & deer.I'm looking @ buying another rifle & was looking @ the 7mm08 but due to ammo availibility I'm leaning more toward the 308.I just prefer short action rifles.
