Depends on the level of effort you want to put into it. I've been working on a hobby project with PostGIS recently, and I've found it very easy to get started (a few hours to get PostGIS running + import just the UK's dataset using osm2pgsql). But it's taken me months to get to a point where I'd say I'm pretty experienced with it.
