@OP, I feel for ya. Been down the same path. Random thoughts:

1) If you stay with the Winchester, +1 on Redneck, and +1 on the Echols Legend. Both are the real deal for Win M70's...
2) Handled a LH ALR at Whittaker's. They have some heft to them. However, for a .338, that is probably not a bad thing. Almost bought one, but bought a RH Kimber Classic Select that they had in stock instead. Retrospect, probably should have waited for the ALR...
3) As I am thinning the herd, my last LH Winchester (.300H&H) is on consignment at a local shop. The last rifles standing will be a two or three LH Rem 700's / clones along with one or two nice LH Mausers. The Mausers because they are unique. The Rem's because of the abundance of parts to tinker with...

That's my story and I am sticking to it... Good luck with which ever option you choose...
