As I said , I have one of each . Also own a couple of 700 BDL (older models) and have had others over the years.
Trigger - from the factory both the Savage & Stevens were better than any of the new 700's I've handled in the past few years. Plus it took me all of 15 minutes to lighten each of them up to where I like them, nice and crisp (equal to what a good gunsmith did on the last 2 700's I had done) and I'm an accountant because I can't do anything useful .
Recoil pad - pretty poor on the Savage and Stevens. Unless you get the R3 on the Remington you aren't doing any better there
Drop floorplate - fair enough depending on your preference, thats a choice thing. Personally the best magazine ever made , for my money, is the old Savage 99 rotary, which is simply a matter of preference and irrelevent any way. So if you prefer the drop floorplate , there you go
Better finish - you looked at the new Remingtons lately ? And , as I said above, have Remington's like them, use them a lot
Calibers - you know the further along I go(and older I get) , the less I pay attention to this. Last couple years I've taken whitetail bucks with 300Savage and seems to work just fine.
Stevens has lots -223;22/250;243/7/08;308;25/06; 30/06;270; 300 Win - Savage pretty much the same
Aftermarket - if thats the way you want to go fine. Quite a bit out there for the Savage as well but whatever floats your boat.
To tell the truth I handled the SPS (including the youth model because I've got a couple kids starting to shoot - niece & grandaughter , with 2 nephews almost there) and it does not, for me , handle as well as the Stevens (or Savage) , it felt 'clubby' and barrel heavy - your results might be different.
I've pulled the new 700's out of a box, cleaned them up, shot them , set the triggers up, floated the barrel, set up a handload, etc. then had them shoot great.
The Stevens & Savage came out of the box and shot 1 - 1 1/2 groups in the first 20 rounds fired with Winchester factory loads that had been sitting in my dad's basement for the last 10 years. A good shot would have done better.
Barrels are nice and smooth, very little copper buildup
So there you go - your results (and prefernces ) might differ.
And 10 years from I'll still have what I have - nice handling, accurate, dependable gun - if you want something different thats cool
Cheers
