I'm fine with both slow and fast progression, as long as there's actually a sense of progression. I detest universal level scaling (Like in Elder Scrolls Oblivion). It ruins any and all sense of accomplishment.
As for having an upper cap, I'd rather not. I'd rather just have it be infinite, so that people are actually rewarded relative to the time and effort they put in.
