I can answer part of this.... I have a Tikka 595 whitetail hunter in 7mm-08 ( and a 695 in 7mmRM). It is a fine gun, smooth action, one of the better triggers to come from a factory. It shoots usually less than an inch at 100 if I do my part. Overall, I think it's a fine gun for the money.
The only Rem 700 I have is a CDL (35 Whelen). I've heard that the 700 triggers may not be the best. I did adjust mine, but it still not exactly where I want it. Guess my gunsmith skills need work. Usually the ADL has iron sights, and the Tikka does not. The Tikka has a removable mag. and the ADL is internal.
With the two guns mentioned being different calibers, that may have some impact into your choice. I am not a 243 fan.
Good luck,
