I looked at the omegas too as Thompson does make good guns. This is what sold me on the V2 versus the omega.
#1 the adjustable trigger. Man it is crisp and sweet.
#2 the stock. I liked the rubber feel of the V2 versus a standard plastic stock that feels cheap. Maybe the omega has the rubber feel to them on different models than I had handled.
#3 The breechplug. I will admit you cannot shoot the standard breech plug with BH209 and that you need to buy the specialty plug however I have shot it over 30 times without swabbing once with no breech plug grease and it comes out with your fingers. That is impressive.
#4 The Bergara Barrel. From everything I have read it is the best of the best. I believe it is true SS. All the others are regular steel with a nickel / stainless coating. The thompsons do have the weathershield. I don't know why but the looks of the weathershield just doesn't do it for me. I like the looks of the fluted barrel versus a standard barrel.
#5. Looks and feel. For me, the V2 just fit me better than the other guns. I love the thumbhole version.
#6 The hammer. All my buddies that have Omegas do not like the hammer in the winter with gloves. It looks small with not a lot to hold on to.
#7 The last inch on the V2 has no rifling either. Very easy to guide a bullet down the barrel.
#8. Absolutely no blowback. After 30 shots with no cleaning I could wipe off where the primer goes in and it was clean as a whistle. I am sure Thompson has this too.
#9 This wasn't until after I bought it but it truly is the most accurate muzzleloader I have ever shot. I will however admit the only guns I have shot previously is my Knight Wolvering, my Knight Disc Extreme and a Remington 700. None of these guns were great at 200 yards. Maybe I never found the right bullet / powder combo for them.

No gun is perfect. Here are the two things I do not like about the V2
#1. I like the quake sling but I do not like the plastic connectors on it. I tried putting a different sling on the gun but the front connector is too wide for a standard steel sling. I need to find a wider version maybe.
#2 I don't really like the ramrod. The Thompson ramrods are awesome for sure. That would be the only win for Thompson just from my perspective when comparing guns.

There is no right or wrong answer. They both will shoot and kill deer just fine. If you would of told me 5 years ago I would be shooting a CVA today I would of bet the farm there wasn't a Chance in H E double hockey sticks that I would shoot one. The Accura V2 and Apex are flat out different to me and ahead of the game. Everyone always mentions that your CVA will blow up. That was what back in 95 or 96 when they had a recall, admitted to the fact they screwed up and have not had any issues since. It is time to move on.
Here is the first 200 yard 3 shot group I ever shot with the gun shooting 120 grains of BH209 and a Barnes 250grain TMZ with a winchester primer. I was shooting off a sandbag so the rest wasn't the best. Works for me.
Choose whatever you like, that is the beauty of competition. Some awesome guns being produced these days!!
