I bought the SSG24. I'm not particularly a fan of Novritsch himself, I haven't really watched many of his videos (apart from when I was deciding whether to buy the gun or not), so it really wasn't a case of 'buying it for the name'. In fact, first thing I did when I opened the package was remove the Novritsch sticker from the case. I respect him for turning a hobby into a paid job, but I'm by no means a fan.
The deciding factor for me was adding up a VSR10 and all the upgrades I wanted, and comparing the price to the SSG. They worked out about the same (of course, I wasn't factoring in import costs for the SSG at the time - doh!).
Overall I'm happy with it. I use it every game, and hit targets as far as anyone else on the field, sometimes further. And I haven't had to do any tinkering. A lot of people like tinkering, it's part of the fun. I don't. I'm rubbish it at, and the best guns I own are the ones that I haven't opened up.
As for comparing it to the SRS, I've never shot an SRS. My only comparison was at RIFT The Ridge, when someone with an SRS (who appeared to be quite experienced) told me I was wasting my time shooting at a group of distant enemies, and that I was well out of range. I politely explained that I'd already hit 6 of them. He didn't believe me, and wouldn't be convinced. Not exactly a water-tight comparison, but it is what it is.
So in answer to your questions, my thoughts on it? Good. Value for money? Maybe not if you can get the parts cheaper and put them together well, but the sums I did said for a little bit extra it all comes ready to go. As someone who just wanted an out-of-box hi-end gun, it ticked all the boxes for me and I don't regret buying it.
