I mean for B&M it's an obvious choice
Drayton Manor!
Gold Reef City is a solid contender too, of course.
Also, for some of the smaller manufacturers:
Reverchon: Gotta go with Wiener Prater here, since they seem to be the only park that ever got two different coasters from these guys. That being said, Wiener Prater isn't so much an amusement park as a parking lot for travelling rides operated by different showmen. On a sidenote, Reverchon coasters tend to be moved around a whole lot, even inside parks. Shout-out to Ice Mountain at Fantasy Island, with four different RCDB listings in that park.
Wiegand: Gotta be Erlebniswelt Seilbahnen Thale for this one - not surprisingly, since Wiegand operates the ... uhh, calling it a "park" would be too generous ... hillside. At a somewhat distant second, I guess Mystic Mountain Jamaica would fit. It has two Wiegand rides. Again, calling them "coasters" would be too generous. Honestly, this manufacturer is really going downhill.
ABC Rides: This is a tricky one, since, despite being the go-to manufacturer for jokes about small and uninteresting coasters, they've only built seven coasters so far. The best-looking of them has to be Achterbahn at Ferienzentrum Schloss Dankern, so I guess this park takes the ABC crown.
Preston & Barbieri: Another manufacturer that hasn't sold a coaster to a park twice. As such, rankings will depend on the park with their best individual coaster. I'm personally partial to Stampbanan at Liseberg, but they've got more interesting coasters out there too. The creatively named Roller Coaster at Fayzaan Park in Dushanbe might be the nicest-looking iteration of their biggest coaster so far.
Pinfari: None. There's no winning this ranking. As a sidenote, I keep being amazed at how prolific this manufacturer continues to be despite kicking the bucket in 2004. Four coasters due to open this year bear their name, two of them in the UK. Pinfari coasters never die, they are just dismantled and sold to the next bigger sucker.
E&F Miler: Uhh ... this one is a very confusing manufacturer to look up, because they tend to sell coasters with very similar names to parks with very similar names, and they tend to get relocated a lot. RCDB has 15 different listings for coasters named Python Pit at places named Jeepers, for instance. I'm going to go with Fun Spot America for this manufacturer, without correcting for the fact there appears to be three parks with that name, with various E&F Miler coasters relocated between them.
Fabbri: Ahh, finally it gets easier again. Two parks feature two running Fabbri coasters. Of the two, I think the edge goes to Zoosafari Fasanolandia. While Fantasy World Almaty also features a really nicely located Astral inverted coaster, Zoosafari Fasanolandia also has a spinning Wild Mouse, where Fantasy World only has an oval kiddie coaster.
Interpark: Pinfari under a new name, with approximately the same level of proficiency. No wonder why they have coasters operating in 28 parks without having managed to sell an additional ride to any of them. The winner here has to be every park that hasn't got one of their coasters.
SBF Visa: I was originally going with Clarence Pier for this one. It's one of the few parks that operate two SBF Visa coasters, and one of them is even the fastest the manufacturer has on record according to RCDB. Although it says a lot that, despite the fact that SBF Visa has 330 coasters under their belt, only 16 of them have a registered speed stat on RCDB. Only two go faster than 50 km/h. About 100 of them have a registered height. Only 6 are taller than 10 meters, of which the tallest caps out at 12. But then I saw Energylandia operates
five of SBF Visa's contraptions. Da heck? Energylandia is definitely the best park to experience SBF Visa coasters, provided such a thing is possible in the first place.
