Best

Eclipse Gemini 2/B9TL (the most comfortable seats)

ALX300 (got these regularly on the 604 as it stopped outside my house when Arriva used to run the Prudhoe services)

Volvo B10BLE (mainly the Lime services and Arriva when they ran them on the 602)

Castles Express Streeetdecks (minus the 50mph limit, interior is one of the best I have seen on a bus)

Leyland National 2 (had these on the old 718 to get to school and back when I lived in Craghead until they were replaced by the Optare Excel which were awful, Always a pleasure to see at bus rallies)

Worst

Eclipse Gemini 1 (especially 3942/3963/3964 could hear it coming before I saw it on Prudhoe front street the other day)

Wright Solar (earlier models, in particular The Waggonway fleet)

Fiat Bluebird

Plaxton Prestige (rattled a lot on the way to Beamish from Newcastle, especially on the the road between Birtley and Ouston)

Optare Excel (made weird creaking noises when they first entered service from what I remember on way back from school)

Volvo Olympian (3822, itchy seats bad ride quality. Haven't been on others so can't comment on them
