Favorite Amiga: 4000, because of it's expandability, only wish is to get an Escom tower 4000, I have a few desktops, Micronik, so only thing I need is proper tower.
Also the 1200 shares that top position.
Even favorite (so not bad, but not great either): 500 / 2000, these are by far the best for games, but they lack the speed.
Although the 2000 has good expandability, the A500 is not, turbo boards are rare and often very expensive.
Least favorite: 1000, although you have hardware kickstarts, most of them are softkick and I can't see my self inserting disks all the time.
I would like to have one just for the collection, but I won't use it.
