Savage 110 by far imo. If you are going to get a 700 an older used one is the only way to go imo.
That said, every 110 I've seen has shot under 1" groups at 100 yards with cheap factory ammo right out of the box, and the one I have shoots under .5" groups with handloads. It shoots .8" groups with Winchester Power Points and Federal Power Shoks.
I've had to deal with Savage customer service on a few ocasions, but not because of anything major. The first time I called to ask to purchase the tool to adjust the accu trigger. They asked for my address and told me it would be no charge. I got it very quickly. The second time I broke the plastic trigger guard. I called up again knowing that the rifle was out of warranty and I was the second owner. Once again they just sent me another one free of charge.
Then the only problem I've had that I feel like I didn't fully cause myself, I had the recoil pad rip after the rifle was out of warranty. It was the super soft one, and while it was me being a tad rough on it that caused it to rip, I still don't think it should have. Knowing it was out of warranty, I asked if there was anything they could do? Their answer, "sure send it in and we will fix or replace it." I had another one back in my hands very quickly this time too.
These rifles are very accurate, great quality, if you get the accu trigger have great triggers, and the company has great customer service. This just sold me.
On the other hand, for Remington while I haven't bought a 700 lately, every Remington I've had or that a friend in our hunting club has bought has had a problem with it out of the box. You call their customer service and their answer? It will be 2-4 months to fix it. Most of the time these guns have been purchased right before hunting season and we haven't had time to wait 2-4 months, not to mention they should have worked properly right out of the box.
That said, I am a fan of the older Remingtons, but I still much prefer the Savages over the 700's.
Something else to mention is that it's hard to judge how accurate they are off of guys at the range if you don't shoot it personally and the groups are poor. The reason I say this is I've run into a ton more shooters that shoot 2-3 MOA groups than I have ones that can shoot sub moa groups. So just because one guy is getting 1.5" groups from his Savage and another gets .5" groups from his Remington at the range, that doesn't mean that's all the Savage is able to do.
