I think you'll probably enjoy the trip no matter what rifle you end up with, pretty hard to happen across a 223 that does not shoot well these days.
The choices are pretty subjective really - my priorities are fit, ease of use, light weight and visual and feel aesthetics = vixen or similar CZ 527 or even a Savage LWH, I'm much more walnut and blued action than the alternatives. I know the current Tikka's shoot well but they just leave me cold in all other regards - it's very subjective.
