Curious about your problems with rings marking the tube. I haven't encountered this with my Warne rings. Have you checked to see if your bases are misaligned? The Weaver bases on my Springfield were not properly aligned due to poor job tapping the receiver by poor quality gunsmith. I had to do significant shimming or turrets would run out. Switching to a rail fixed the issue.
I think if one is considering changing scopes on the fly, you should go with quick detach if deciding for Warne rings. Yes, their vertically split standard rings are not handy for this. My Warne QD rings cost ~$80 ($60 US) which is quite reasonable. Not sure their non-QD rings would be any cheaper. As I said, these QD rings hold zero very well. Not sure I would trust swapping scopes with half the standard rings staying mounted to rifle. The scope is never going to reattach to the rifle in exactly the same place the same way. To get it even close to zero, the scope and ring base would both need to be marked before the scope is removed. With QD rings, the rings and scope remain a single unit when the scope is removed. As long as the bases/rail doesn't change (and it shouldn't if properly mounted), the scope(s) should retain zero and eye relief should remain unchanged.
