This sounds as though you're talking strictly about soldering them to a
printed-circuit board. If so, that's a lose right there, compared to
DIPs, if you can't connect to them (without equipment prohibitively
expensive for hobbyist use) except via a PCB.

Components with small "pin" count and large "pins", like passives or
discrete transistors, are comparatively easy, yes. But still not
*nearly* as easy as the corresponding components designed for
through-hole use (and readily usable for other, eg, point-to-point,
use, which SM components generally aren't; while for "easy" components
it's not all that hard to solder leads onto them, at the very least
it's an extra step, and in general I'd say it qualifies as "harder").
