I dont own a TC in the carbine, but I do have a contender G2 in the handgun, but the funtionality is the same as far as the frame goes.
I like the TC as far a the barrel catch goes, pretty handy but can snag on stuff, that I dont like, though the catch on the NEF is just as easy to use and I dont recall ever snagging it on anything, the hammers though are a diff story
strengthwise, the TC is most likely the stronger...
Handi has slimmer styling and a good amount of stock options if your willing to look.
the TC isnt as streamlined and stock options are pistol grip, or thumbhole pistol grip.
More barrel/caliber options with the TC, and more so with the custom barrel makers added in.
accuracy, its debatable in the stock barrels from both factories mine have been good, some have had different experiences with each. obviously the custom barrels are expected to be far better than factory. (remember my barrels were for a pistol)
cost, for less than a new TC barrel, I can just go and buy the whole new handi rifle, or send it in (can be a pain at times from what ive heard) and get a barrel fitted for alot cheaper than a TC barrel, again optional chamberings are less.
Finish, gonna have to say the TC is better, in most cases that is. Handis are plain ol work horses, pretty means mo money!
Have never dealt with TC CS but before the buyout, HR/NEF was fantastic! now, well my experience is not so good, but not bad enough to keep me from getting more (not warranty issues, bought some extras/parts and they goofed it all up, Twice!)
Both are terribly addicting!!!!
I prefer my handis, will not get a tc carbine/rifle, too costly for what I get out of it, and anything I need cartridge wise I can get from a Handi. That being said Ill never get rid of the pistol, but that is a different apple.
good luck with whatever decision your making, these are just my own opinions, Im sure some have a different take on it.
