In the collection I had before Intel took over the world (Jupiter Ace, Oric Atmos, ZX80, 81, Spectrum, Spectrum+, Vic20, C64, D32 (twice), Amiga and Osborne) the best two for writing games were the Dragon and the BBC. For playing games, the Amiga and the Spectrum probably edged ahead through number of titles, and the Ace and the Osborne were most challenging for real programming fun.

IMHO

(wasn't really wanting a flamewar)

p.s.I'm sure my first Dragon was the world's most travelled - over 20,000 miles in its 2nd year...I was travelling to the Falklands and back a fair bit...so when it finally died, Dragon replaced it for free even though it was out of warranty and the shipping to the south Atlantic must have been heinous
