My friend
Go out and shoulder some rifles,shoot them if you can,talk to others but in the end,every gun mentioned will go BOOM and kill game.
I think now a days we are talking more about fit and finish and small features that make a rifle desireable to you than anything else.
Buy the one YOU LIKE and buy it.
If it were me I would not buy a discontinued rifle but that's me.
Have fun and good luck
