Which KitchenAid stand mixer would you purchase amongst:

Classic 8 cup / 4.5 qt / 250W
Ultra Power 8 cup / 4.5 qt / 300W
Artisan 9 cup / 5 qt / 325W

All are tilt head
For the purposes of discussion ignore the (IMO, insignificant) price
difference amongst these product lines.

(Accolade is too expensive for my needs)



What I plan to make:
pizza dough
pasta dough
chapati
cookies
pancakes
cake from mix


relatively small quantities so even 8 cup will be plenty of capacity

I'm finding when using my hand mixer I end up needing another hand! (as
well as making a big mess)

any comments will be appreciated but I will only be considering the
KitchenAid brand for this purchase

thanks
