FAC has been granted in principal, subject to security which is sorted now, so slowly getting there.

I have a couple of - potentially silly - questions about optics.
1. Am I correct in thinking that unless you're using the mildots for range finding, FFP vs SFP is purely a matter of personal preference? Or am I missing something else? I understand the difference between the two(lots of Internet reading over the last few days), but there doesn't seem to be a definitive answer if one is better than the other. Just plenty of people saying they prefer one over the other.
2. Lots of people at the LPSC use Schmidt & Bender scopes and swear by them. Are they really that much better than a much cheaper scope?? I know they're expensive and it would be a stretch for me to buy one at the same time as a new rifle, but would it be worth it? I don't mind paying a lot for good quality that will pay for itself over time. Also, I do believe that some expensive items can still be good value, if that makes sense. So my question is, rather than spending £1000 or £1500, should I just stump up the extra and go for a S&B? The reasoning in my mind is that I could spend a lot of time and money not making the most of my shooting, if my optics are dodgy.
Comments/advice much appreciated.

Cheers,
Jud
