Wonka SE looks awesome for the money and some people were quick to take jabs at Oktoberfest over in the Wonka thread. It does look like a great option. Wonka has better art and animations but, feature-to-feature, it appears that Oktoberfest has MORE stuff and new ideas in the mechanicals.
Here's what's in the Fest:
Ramp that raises and lowers
Rollercoaster Shack physical 3 ball lock
Upper Flipper
180 Ramp that feeds into lock
Beer Barrel physical 3 ball lock
Bar Toy that you bash to open then hit into bar and drop into the toy, Otto head spins (hmmm... functionally similar to the Goobstopper toy)
Two VUKs to some of the most interesting wireforms - clearly more interesting that Wonka wireframes
PROST bank of 5 slim line targets
OKTOBER bank of 7 slim line targets in crescent formation
FEST bank of 4 slim line targets also in crescent formation
3 Duck Targets
Full RGB LEDs on playfield and GI
4 Magnets
MagNab with 3rd button next to right flipper - right hand only mode
3 lanes into a 3 pop bumper nest
6 speaker audio plus 8" sub
I may end up with a BKSoR or a Wonka but I'm not going to dismiss Oktoberfest either - ton of stuff on that playfield and I love the beer and brats atmosphere of the Fest. Having not played it I hope I'm wrong but I just don't see anything revolutionary in Wonka. I think Balcer pushed the envelope just a bit more that Lawlor.
