Yes, LCH is easier to use for picking colors than other CIELAB color spaces. To try an LCH color picker, you can use http://davidjohnstone.net/pages/lch-lab-colour-gradient-pick... (as linked in another comment).

You can also use the better-implemented color picker for the HSLuv color space at http://www.hsluv.org/. HSLuv is just like LCH except that it stretches the saturated colors for each hue so that any saturation coordinate represents a valid color, unlike LCH’s chroma coordinate. The downside is that the color’s chroma (colorfulness) can change when you drag the hue slider.
