I feel quite lucky to have ticked off four of the six in this group, though none of my last rides could be called particularly recent. I voted for Stunt Fall and El Toro.
I'd imagine those that have visited parks in the states would say Plohn's El Toro is not a patch on the Intamin one, and pretty average for a GCI. I however found it to be a damn good ride with a good mix of proper airtime hills and nice corners (aside from one, the fourth bend I think, which manages that Gersty thing of rattling your brain in your skull despite not being conventionally rough; Troy was like that in places when I first did it). It's no Wodan or Troy, but for me it's a cut above Joris and particularly Wicker Man.
With other competition I probably wouldn't have voted for Stunt Fall, because when you ride THE GIB! it feels only just well enough engineered to work. In fact, quite often it seems these rides don't. I know we felt blessed to get on back in 2015. It's not remotely refined, even by early 2000s Vekoma standards. You'll notice how in the video there's no holding brake on the lifts, the train merely dropping you to your doom when the chain's done its thing, and that there's a disconcerting clunk from the train starting to go back down perhaps an inch or two before the second lift catches it. Why did I vote for it then? Not just because this ride type is a TS legend (other examples of THE. GIB. can be found at GIBneyland Paris and Cologne GIBthedral). It's mindbogglingly massive, requires you to blend actively riding with the train and cowering in your seat, and is just unbelievably terrifying.
As usual, the rest:
Megafobia - usually this is merely a good ride. If you go to a late close day and wait around long enough, it might become a really amazing, great memory making, I'll-even-buy-a-mug level of ride, but if you have to wait around that long (at a dump like Oakwood of all places) on a certain type of day, it doesn't seem right to rate it highly on that basis.
Baron - I love the theme and preshows. Unfortunately the layout after emerging from the tunnel feels like it exists just so that something happens afterwards, and unlike Valkyria, none of that something is very interesting or thrilling.
Raptor - those that have ventured to the beauty of Lake Garda and its surroundings to visit a Merlin park tell me this still might be the best wing coaster for interaction with theming elements. It looks fine, but less interesting layout-wise than Flug der Damonen which I didn't think deserved to go through either.
Nefeskesen - this is an Intamin with an odd layout. It seems completely impossible to tell whether it's brilliant or awful from a POV, so I'll perhaps unfairly assume the latter for now.
