Without getting into whether I like the change or not, overall IMO it does add to the choices. 1hr/lvl meant that was the just about the only 2nd level spell a wizard or sorcerer cast in every campaign I've ever been in, which meant there were no choices re 2nd level spells, just a choice of which buff was more important. Mirror image, web, and alter self were sometimes used, but not very much, and once in a blue moon something else was used. Same with clerics, they were buffcasters by and large. Actually, for sorcerers, except for mirror image and web, I never saw one learn a 2nd level spell exc. for buffs.
There also was no "choice" re stat buff items. You were foolish if you bought one instead of getting a big-ass sword or something, and let the spells be used instead. So, unless you felt some compulsion for idiocy, you wouldn't waste money on stat items. The "choice" boiled down to foolishly wasting resources, or spending wisely. Much like you can "choose" to play a wizard with a 10 intelligence, if you want.
