Any of them (and I'm not trying to kiss up.... it's just true lol). I like certain Designers for certain themes, and I find I tend to scrap seasonally (like in summer I scrap all summer photos, current and past winter all so and christmas photos etc), so I find myself using a handful of designers all summer long, then I switch gear to completely different designers for differet seasons if that makes sense, so if it seems like I am working with designs from just a couple of designers lately, just wait another month and I'm sure to switch gears.... LOL So because of the way I work.... my preferences change regularly so I don't even know where to begin on choosing a few, let alone just ONE.
